60e7fa8b3b treewide: convert devfdt_get_addr() to dev_read_addr()
When you enable CONFIG_OF_LIVE, you will end up with a lot of
conversions.

To generate this commit, I used coccinelle excluding drivers/core/,
include/dm/, and test/

The semantic patch that makes this change is as follows:

  <smpl>
  @@
  expression dev;
  @@
  -devfdt_get_addr(dev)
  +dev_read_addr(dev)
  </smpl>

3c12c62ba5 treewide: convert (void *)devfdt_get_addr() to dev_read_addr_ptr()
Use the _ptr suffixed variant instead of casting. Also, convert it to
dev_read_addr_ptr(), which is safe to CONFIG_OF_LIVE.

One curious part is an error check like follows in
drivers/watchdog/omap_wdt.c:

    priv->regs = (struct wd_timer *)devfdt_get_addr(dev);
    if (!priv->regs)
            return -EINVAL;

devfdt_get_addr() returns FDT_ADDR_T_NONE (i.e. -1) on error.
So, this code does not catch any error in DT parsing.

dev_read_addr_ptr() returns NULL on error, so this error check
will work.

I generated this commit by the following command:

 $ find . -name .git -prune -o -name '*.[ch]' -type f -print | \
   xargs sed -i -e 's/([^*)]*\*)devfdt_get_addr(/dev_read_addr_ptr(/'

I manually fixed drivers/usb/host/ehci-mx6.c

b75d8dc564 treewide: convert bd_t to struct bd_info by coccinelle
The Linux coding style guide (Documentation/process/coding-style.rst)
clearly says:

  It's a **mistake** to use typedef for structures and pointers.

Besides, using typedef for structures is annoying when you try to make
headers self-contained.

Let's say you have the following function declaration in a header:

  void foo(bd_t *bd);

This is not self-contained since bd_t is not defined.

To tell the compiler what 'bd_t' is, you need to include <asm/u-boot.h>

  #include <asm/u-boot.h>
  void foo(bd_t *bd);

Then, the include direcective pulls in more bloat needlessly.

If you use 'struct bd_info' instead, it is enough to put a forward
declaration as follows:

  struct bd_info;
  void foo(struct bd_info *bd);

Right, typedef'ing bd_t is a mistake.

I used coccinelle to generate this commit.

The semantic patch that makes this change is as follows:

  <smpl>
  @@
  typedef bd_t;
  @@
  -bd_t
  +struct bd_info
  </smpl>

51f1263d89 dtoc: extend dtoc to use struct driver_info when linking nodes
In the current implementation, when dtoc parses a dtb to generate a struct
platdata it converts the information related to linked nodes as pointers
to struct platdata of destination nodes. By doing this, it makes
difficult to get pointer to udevices created based on these
information.

This patch extends dtoc to use struct driver_info when populating
information about linked nodes, which makes it easier to later get
the devices created. In this context, reimplement functions like
clk_get_by_index_platdata() which made use of the previous approach.

addf358bac core: add support for U_BOOT_DRIVER_ALIAS
Currently when using OF_PLATDATA the binding between devices and drivers
is done trying to match the compatible string in the node with a driver
name. However, usually a single driver supports multiple compatible strings
which causes that only devices which its compatible string matches a
driver name get bound.

To overcome this issue, this patch adds the U_BOOT_DRIVER_ALIAS macro,
which generates no code at all, but allows an easy way to declare driver
name aliases. Thanks to this, dtoc could be improve to look for the driver
name based on its alias when it populates the U_BOOT_DEVICE entry.

e3e2470fdd drivers: rename drivers to match compatible string
When using OF_PLATDATA, the bind process between devices and drivers
is performed trying to match compatible string with driver names.
However driver names are not strictly defined, and also there are different
names used when declaring a driver with U_BOOT_DRIVER, the name of the
symbol used in the linker list and the used in the struct driver_info.

In order to make things a bit more clear, rename the drivers names. This
will also help for further OF_PLATDATA improvements, such as checking
for valid driver names.

ba61676ff9 mmc: fsl_esdhc_imx: disable the CMD CRC check for standard tuning
In current code, we add 1ms dealy after each tuning command for standard
tuning method. Adding this 1ms dealy is because USDHC default check the
CMD CRC and DATA line. If detect the CMD CRC, USDHC standard tuning
IC logic do not wait for the tuning data sending out by the card, trigger
the buffer read ready interrupt immediately, and step to next cycle. So
when next time the new tuning command send out by USDHC, card may still
not send out the tuning data of the upper command,then some eMMC cards
may stuck, can't response to any command, block the whole tuning procedure.

If do not check the CMD CRC for tuning, then do not has this issue. USDHC
will wait for the tuning data of each tuning command and check them. If the
tuning data pass the check, it also means the CMD line also okay for tuning.

So this patch disable the CMD CRC check for tuning, save some time for the
whole tuning procedure.

The 3V3/1V8 switching could never have worked on any of the iMXes
ever since 51313b49f2 ("mmc: fsl_esdhc: support SDR104 and HS200"),
because that commit uses priv->vqmmc_dev when switching voltages on
mode switch, while local vqmmc_dev in probe to store the regulator
pointer. Those are two different variables with the same name. So
the priv->vqmmc_dev was always NULL and thus voltage switch between
modes never really suceeded.

Fix this by assigning priv->vqmmc_dev with value of the vqmmc_dev
in probe.

c927d65873 mmc: fsl_esdhc: workaround for hardware 3.3v IO reliability issue
When eSDHC operates at 3.3v, damage can accumulate in an internal
level shifter at a higher than expected rate. The faster the interface
runs, the more damage accumulates. This issue now is found on LX2160A
eSDHC1 for only SD card.

The hardware workaround is recommended to use an on-board level shifter
that is 1.8v on SoC side and 3.3v on SD card side.

For boards without hardware workaround, this option could be enabled,
ensuring 1.8v IO voltage and disabling eSDHC if no card.
This option assumes no hotplug, and u-boot has to make all the way to

Cleanup this driver to use dt in U-boot and static platdata in SPL.
This requires the following steps:

1. Move all platdata assignment from probe() to ofdata_to_platdata().
   This function is only called in U-boot.
2. Replicate all the platdata assignment being done in
   ofdata_to_platdata() in the omapl138 board file. This data is used in
   the SPL case where SPL_OF_CONTROL is not enabled.
3. Remove SPL_OF_CONTROL and related configs from omapl138_lcdk_defconfig

This cleanup effectively reverts 3ef94715cc ('mmc: davinci: fix mmc boot in SPL')

4a66d4ee33 mmc: tmio: sdhi: Implement get_b_max function
Implement get_b_max() for the Renesas R-Car SDHI controller driver, limit
the b_max per hardware capabilities such that select Gen2 controllers have
16bit block transfer limit, the rest has 32bit block transfer limit and on
Gen3, the block transfer limit on addresses above the 32bit boundary is set
to 1/4 of the malloc area.

Originally, on Gen3, the block transfers above the 32bit area were limited
to PIO only, which resulted in (R8A7795 Salvator-X , HS200 eMMC):
  => time mmc read 0x0000000700000000 0 0x10000
  time: 0.151 seconds
  => time mmc read 0x0000000700000000 0 0x100000
  time: 11.090 seconds
with bounce buffer in place and b_max adjustment in place:
  => time mmc read 0x0000000700000000 0 0x10000
  time: 0.156 seconds
  => time mmc read 0x0000000700000000 0 0x100000
  time: 2.349 seconds

Note that the bounce buffer does mallocate and free the bounce buffer
for every transfer. Experiment which removes this results in further
increase of read speed, from 2.349s to 2.156s per 512 MiB of data,
which is not such a significant improvement anymore. It might however
be interesting to have bounce buffer directly in the MMC core or even
block core.

145429aac0 mmc: Add option to adjust b_max before long read
Add getter function which permits adjusting the maximum number of
blocks that could be read in a single sustained read transfer based
on the location of the source/target buffer and length, before such
transfer starts.

This is mainly useful on systems which have various DMA restrictions
for different memory locations, e.g. DMA limited to 32bit addresses,
and where a bounce buffer is used to work around such restrictions.
Since the U-Boot bounce buffer is mallocated, it's size is limited
by the malloc area size, and the read transfer to such a buffer must
also be limited. However, as not all areas are limited equally, the
b_max should be adjusted accordinly as needed to avoid degrading
performance unnecessarily.

a482f32992 mmc: t210: Fix 'bad' SD-card clock when doing 400KHz card detect
According to the HW team, for some reason the normal clock select code
picks what appears to be a perfectly valid 375KHz SD card clock, based
on the CAR clock source and SDMMC1 controller register settings (CAR =
408MHz PLLP0 divided by 68 for 6MHz, then a SD Clock Control register
divisor of 16 = 375KHz). But the resulting SD card clock, as measured by
the HW team, is 700KHz, which is out-of-spec. So the WAR is to use the
values given in the TRM PLLP table to generate a 400KHz SD-clock (CAR
clock of 24.7MHz, SD Clock Control divisor of 62) only for SDMMC1 on
T210 when the requested clock is <= 400KHz. Note that as far as I can
tell, the other requests for clocks in the Tegra MMC driver result in
valid SD clocks.

a851213920 mmc: am654_sdhci: Implement workaround for card detect
The 4 bit MMC controllers have an internal debounce for the SDCD line
with a debounce delay of 1 second. Therefore, after clocks to the IP are
enabled, software has to wait for this time before it can power on the
controller.

Add a deferred_probe() callback which polls on sdcd for a maximum of 2 seconds
before switching on power to the controller or (in the case of no card)
returning a ENOMEDIUM. This pushes the 1 second wait time to when the
card is actually needed rather than at every probe() making sure that
users who don't insert an SD card in the slot don't have to wait such a
long time.

4155ad9aac mmc: sdhci: fix missing cache invalidation after reading by DMA
This driver currently performs cache operation before the DMA start,
but does nothing after the DMA completion.

When reading data by DMA, the cache invalidation is needed also after
finishing the DMA transfer. Otherwise, the CPU might read data from
the cache instead of from the main memory when speculative memory read
or memory prefetch occurs.

Instead of calling the cache operation directly, this commit adds
dma_unmap_single(), which performs cache invalidation internally,
but drivers do not need which operation is being run.

Currently, sdhci_prepare_dma() calls flush_cache() regardless of the

Actually, cache invalidation is enough when reading data from the device.

This is correctly handled by dma_map_single(), which mimics the DMA-API
in Linux kernel. Drivers can be agnostic which cache operation occurs
behind the scene.

This commit also sanitizes the difference between the virtual address
and the dma address.

9d86b89c59 dma-mapping: move dma_map_(un)single() to <linux/dma-mapping.h>
The implementation of dma_map_single() and dma_unmap_single() is
exactly the same for all the architectures that support them.

Factor them out to <linux/dma-mapping.h>, and make all drivers to
include <linux/dma-mapping.h> instead of <asm/dma-mapping.h>.

If we need to differentiate them for some architectures, we can
move the generic definitions to <asm-generic/dma-mapping.h>.

Add some comments to the helpers. The concept is quite similar to
the DMA-API of Linux kernel. Drivers are agnostic about what is
going on behind the scene. Just call dma_map_single() before the
DMA, and dma_unmap_single() after it.

ede2822864 mmc: fsl_esdhc: actually enable cache snooping on mpc830x
The reference manuals for MPC8308 and MPC8309 both say that the
esdhcctl aka DMA Control Register "is implemented as SDHCCR" in the
System configuration registers. Unfortunately, that doesn't mean that
the registers are just mirrors of each other - any write to esdhcctl
is simply ignored. So to actually enable cache snooping, we
unfortunately have to add a little ifdeffery.

There is, naturally, no description of the bit fields of esdhcctl in
the MPC8309 manual, but comparing the description of esdhcctl from the
LS1021A reference manual to the description of the sdhccr in MPC8309,
one also finds that the fields are bit-reversed, so the bit to set is
0x02000000 rather than 0x00000040 - this is also what board_mmc_init()
uses in the two gdsys/mpc8308/ boards.

54a78cbdbe mmc: sdhci-cadence: send tune request twice to work around errata
Cadence sent out an errata report to their customers of this IP.
This errata is not so severe, but the tune request should be sent
twice to avoid the potential issue.

Quote from the report:

Problem Summary
---------------
The IP6116 SD/eMMC PHY design has a timing issue on receive data path.
This issue may lead to an incorrect values of read/write pointers of
the synchronization FIFO. Such a situation can happen at the SDR104
and HS200 tuning procedure when the PHY is requested to change a phase
of sampling clock when moving to the next tuning iteration.

Workarounds
-----------
The following are valid workarounds to resolve the issue:

1. In eMMC mode, software sends tune request twice instead of once at
   each iteration. This means that the clock phase is not changed on
   the second request so there is no potential for clock instability.
2. In SD mode, software must not use the hardware tuning and instead
   perform an almost identical procedure to eMMC, using the HRS34 Tune
   Force register.

requires including linux/compat.h which in turn includes a lot of headers.
One of these is malloc.h which we thus end up including in every file in

which needs to use the system malloc() in some files.

a20008eabd mmc: am654_sdhci: Add Support for configuring PHY in J721e
Add Support for writing to PHY registers for J721e. There are number of
differences between the J721e 8 bit PHY, J721e 4 bit PHY and AM654 PHY.
Create a driver_data structure with an ops and flags field and use the
flags field to indicate these differences. The differences are as
follows:

1. The J721e 4 bit instance PHY does not have a DLL. Introduce a
DLL_PRESENT flag to make sure that DLL related registers are accessed
only where they are present. Also add a separate set_ios_post()
callback.

2. The J721e 8 bit instance is not muxed with anything else inside the
SoC and hence the IOMUX_ENABLE filed does not exist. Add a flag which is
used to indicate the presence of this field.

3. The register field used to select DLL frequency is 3 bit wide in
J721e as compared to 2 bits in AM65x. Add another flag that
distinguishes these fields.

4. The strobe select field is 8 bit wide as compared to 4 bit wide for
AM65x. Add yet another flag to indicate this difference. Strobe select
is used only for HS400 speed mode, support for which has not been added
in AM65x.

bcee8d6764 dm: gpio: Allow control of GPIO uclass in SPL
At present if CONFIG_SPL_GPIO_SUPPORT is enabled then the GPIO uclass
is included in SPL/TPL without any control for boards. Some boards may
want to disable this to reduce code size where GPIOs are not needed in
SPL or TPL.

Add a new Kconfig option to permit this. Default it to 'y' so that
existing boards work correctly.

Change existing uses of CONFIG_DM_GPIO to CONFIG_IS_ENABLED(DM_GPIO) to
preserve the current behaviour. Also update the 74x164 GPIO driver since
it cannot build with SPL.

This allows us to remove the hacks in config_uncmd_spl.h and

like for example the soc-internal sram but during boot parts of
TrustedFirmware need to be placed there from the read FIT image.

The regular fifo-mode property still takes precedent and only
if not set do we check for the spl-specific property.

3602a56ac6 mmc: add a driver callback for power-cycle
Some MMC peripherals require specific power cycle sequence, where some
registers need to be written between the regulator is turned off and then
back on. This is the case for the MMC IP embedded in STM32MP1 SoC.

In STM32MP157 reference manual [1], the power cycle sequence is:
1. Reset the SDMMC with the RCC.SDMMCxRST register bit. This will reset
the SDMMC to the reset state and the CPSM and DPSM to the Idle state.
2. Disable the Vcc power to the card.
3. Set the SDMMC in power-cycle state. This will make that the
SDMMC_D[7:0], SDMMC_CMD and SDMMC_CK are driven low, to prevent the card
from being supplied through the signal lines.
4. After minimum 1ms enable the Vcc power to the card.
5. After the power ramp period set the SDMMC to the power-off state for
minimum 1ms. The SDMMC_D[7:0], SDMMC_CMD and SDMMC_CK are set to
drive “1”.
6. After the 1ms delay set the SDMMC to power-on state in which the
SDMMC_CK clock will be enabled.
7. After 74 SDMMC_CK cycles the first command can be sent to the card.

The step 3. cannot be handled by the current framework implementation.
A new callback (host_power_cycle) is created, and called in
mmc_power_cycle(), after mmc_power_off().

The incorrect power cycle sequence has shown some boot failures on
STM32MP1 with some SD-cards, especially on cold boots when the input
frequency is low (<= 25MHz).
Those failures are no more seen with this correct power cycle sequence.

80f02019ee spl: dm_mmc: Initialize only the required mmc device
In SPL, all the available mmc devices gets initialized during boot.
This might not work in cases where clocks are not available for
certain mmc devices(other than boot device) and the support for
enabling device might not be ready.

Texas Instruments' K3 J721E device having a central system controller
(dmsc) is one such example falling in this category. Below is the
sequence for the failing scenario:
- ROM comes up in SD mode and loads SPL by just initialing SD card.
- SPL loads dmsc firmware from SD Card.
Since ROM has enabled SD, SPL need not enable the SD, just need
to re initialize the card. But SPL is trying to initialize other MMC
instances which are in disabled state. Since dmsc firmware is not yet
available, devices cannot be enabled. So in SPL, initialize only the
mmc device that is needed.

cf31914cf2 mmc: Replace printf with debug call for timeouts in the i.MX28 mxs driver
This change replaces printf() with debug() for the notification about
commands timeouts.

This is done on purpose (also other drivers use such approach - dw_mmc.c,
mvebu_mmc.c), as the mmc core code (mmc.c) uses timeouts to assess if one
is using sd card or eMMC device.
In such situation timeout is a some kind of a "normal" behavior and there
shall not be any output to the console.

There is no impact on boot time for boards using this driver (even in SPL)
when two extra timeouts are returned (no SD card present, only eMMC
available).

Boot time tested with grabserial:
sudo grabserial -b 115200 -d /dev/ttyUSB1 -e 30 -t -m "^U-Boot SPL*"

platform clock and peripheral clock
Peripheral clock can provide higher clock frequency
which is required to be used for tuning of SD UHS mode
and eMMC HS200/HS400 modes.

Peripheral clock is enabled by default by defining config
option FSL_ESDHC_USE_PERIPHERAL_CLK if eMMC HS200/HS400 modes

Function bcm_2835_wait_transfer_complete() is not waiting long enough.
The previous code was claiming to wait for ~1 seconds, but as it depends
on register reads it's time actually varies.
Some cards require wait times of up to ~56 ms to perform
the command 'saveenv' on an EXT4 partition.

Re-implement the loop exit condition to use get_timer() which allows
to specify the wait time in more reliable manner. Set the maximum wait
time to the originally intended 1 second.

c077c057a4 mmc: dw_mmc: fix timeout calculate method
There are two cases not been considered:
- use uint for timeout, it will overflow when size bigger than 512KB for
  it *8*1000 at the beginning, but we may use size up to 32MB; The
  'timeout' will overflow if size bigger than 51.2MB after this fix, which
  should be enough for U-Boot;
- The timeout is using clock speed for data rate, but the device may not
  have such high speed, eg. clock is 52MHz while the device write speed may
  be less than 10MB/s, and we may use up to 150MHz clock.

Fix them in this patch, the max timeout is about 6500 when size is 32MB
after fix.

6cf8a903c5 mmc: Rename timeout parameters for clarification
It's quite hard to figure out time units for various function that have
timeout parameters. This leads to possible errors when one forgets to
convert ms to us, for example. Let's rename those parameters
correspondingly to 'timeout_us' and 'timeout_ms' to prevent such issues
further.

While at it, add time units info as comments to struct mmc fields.

This commit doesn't change the behavior, only renames parameters names.
Buildman should report no changes at all.

47b7fa30c4 mmc: invalidate block cache after hwpart switched successfully
eMMC device has multiple hw partitions both address from zero. However the
mmc driver lacks block cache invalidation for switch hwpart. This causes a
problem that data of current hw partition is cached before switching to
another hw partition. And the following read operation of the latter hw
partition will get wrong data when reading from the addresses that have
been cached previously.

To solve this problem, invalidate block cache after a successful
mmc_switch_part() operation.

58d65d5082 mmc: sdhci: fix chip detect gpio property name
The standard property name for chip-detect gpio is "cd-gpios". All
in-tree DT files use only this name.

41a9fab8da mmc: mv_sdhci: fix uninitialized pointer deref on probe
Since commit 3d296365e4 ("mmc: sdhci: Add support for
sdhci-caps-mask") sdhci_setup_cfg() expects a valid sdhci_host mmc
field. Move the mmc field initialization before sdhci_setup_cfg()
call to avoid crash on mmc pointer dereference.

794453f91d mmc: am654_sdhci: Separate J721E compatible into 8bit and 4bit versions
The j721e 4 bit instances don't have a hard DLL and therefore don't need
any DLL related configurations. Split the compatibles into an 8 bit and a
4 bit one. Add a private flags field which can be used to check if the
DLL is present and don't register the set_ios_post callback for the 4 bit
compatible instances.

Also update the compatibles in k3-j721e-main.dtsi to avoid breaking boot
with the new compatibles.

a706029410 mmc: mmc_spi: Use SPI_XFER_BEGIN and SPI_XFER_END flags
Most DM based SPI host controller drivers use SPI_XFER_BEGIN and
SPI_XFER_END flags to enable/disable slave chip select.

This patch extends MMC SPI driver to pass SPI_XFER_BEGIN flag when
MMC command is send at start and pass SPI_XFER_END flag using a
dummy transfer (of bitlen = 0) at the end of MMC command.
