This fixes the issues with calculation of controller indexes in

placed next to each other, and their addresses incremented by 0x10000.
Example of USB nodes for iMX7S/D:
usbotg1: usb@30b10000 {
compatible = "fsl,imx7d-usb", "fsl,imx27-usb";
reg = <0x30b10000 0x200>;

usbotg2: usb@30b20000 {
compatible = "fsl,imx7d-usb", "fsl,imx27-usb";

compatible = "fsl,imx7d-usb", "fsl,imx27-usb";
reg = <0x30b30000 0x200>;

Currently the host driver used by dwc3-generic is "xhci-dwc3". This is
a functional driver but it doesn't use the dwc3 core and, in particular,
it lacks some bits that may be important.
For example on the k2 platforms, it is important that the phy are properly
suspended when the USB is not used anymore. The dwc3 core also has a
partial support for quirks.
The new driver can be used as a drop-in replacement for "xhci-dwc3".
In terms of implementation, it may seem strange that 2 private structures
dwc3_generic_host_priv and dwc3_generic_priv) are used. The reason for this
is simply that the xhci layer expects a struct xhci_ctrl at the beginning
of the private data and it seemed wasteful to include it also for the
peripheral case.

Make sure that the clock self-assignment works by having a clock of

This fixes the case where assigned-clocks is used to define a clock
defaults inside this same clock's node. This is used sometimes to setup a
default parents and/or rate for a clock.
example:
muxed_clock: muxed_clock {
clocks = <&clk_provider 0>, <&clk_provider 1>;
#clock-cells = <0>;
assigned-clocks = <&muxed_clock>;
assigned-clock-parents = <&clk_provider 1>;
};
It doesn't work in u-boot because the assigned-clocks are setup *before*
the clock is probed. (clk_set_parent() will likely crash or fail if called
before the device probe function)
Making it work by handling "assigned-clocks" in 2 steps: first before the
clk device is probed, and then after the clk device is probed.

The Broadcom ARM implementations do not yet have a clock framework so
one can use a fixed clock as the root clock of the hsspi block. The
fixed clock does not have an "enable" routine, since it's always
enabled. So when we hit this issue, getting an ENOSYS return, do not
bail but continue initialization.
Similarly the block might already have been out of reset, say, when
we are booting from a SPI device. So if the reset signal is not configured
in the device tree, do not bail out and instead skip deasserting the reset.

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.

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.

This is done on purpose (also other drivers use such approach - dw_mmc.c,

In such situation timeout is a some kind of a "normal" behavior and there

Sandbox pci works using emulation drivers which are currently children of
the pci device:
pci-controller {
pci@1f,0 {
compatible = "pci-generic";
reg = <0xf800 0 0 0 0>;
emul@1f,0 {
compatible = "sandbox,swap-case";
};
};
};
In this case the emulation device is attached to pci device on address
f800 (device 1f, function 0) and provides the swap-case functionality.
However this is not ideal, since every device on a PCI bus has a child
device. This is only really the case for sandbox, but we want to avoid
special-case code for sandbox.
Worse, child devices cannot be probed before their parents. This forces
us to use 'find' rather than 'get' to obtain the emulator device. In fact
the emulator devices are never probed. There is code in
sandbox_pci_emul_post_probe() which tries to track when emulators are
active, but at present this does not work.
A better approach seems to be to add a separate node elsewhere in the
device tree, an 'emulation parent'. This could be given a bogus address
(such as -1) to hide the emulators away from the 'pci' command, but it
seems better to keep it at the root node to avoid such hacks.
Then we can use a phandle to point from the device to the correct
emulator, and only on sandbox. The code to find an emulator does not
interfere with normal pci operation.
Add a new UCLASS_PCI_EMUL_PARENT uclass which allows finding an emulator
given a bus, and finding a bus given an emulator. Update the existing
device trees and the code for finding an emulator.
This brings PCI emulators more into line with I2C.

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.

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.

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.

With commit c6d07bf440 ("net/macb: increase RX buffer size for GEM")
ethernet support does not work any more with d-cache enabled on the

to 128 but this change was not refected in the rx_buffer flush and
invalidate functions, as these also use this macro.
This patch now fixes this by calculating the rx buffer size correctly

This patch adds a separate driver for the MDIO interface of the
Marvell Ethernet controllers based on driver model. There are two
reasons to have a separate driver rather than including it inside
the MAC driver itself:
*) The MDIO interface is shared by all Ethernet ports, so a driver
must guarantee non-concurrent accesses to this MDIO interface. The
most logical way is to have a separate driver that handles this
single MDIO interface, used by all Ethernet ports.
*) The MDIO interface is the same between the existing mv643xx_eth
driver and the new mvneta/mvpp2 driver. Even though it is for now
only used by the mvneta/mvpp2 driver, it will in the future be
used by the mv643xx_eth driver as well.
This driver supports SMI IEEE for 802.3 Clause 22 and XSMI for IEEE
802.3 Clause 45.
This patch also adds device tree binding for marvell MDIO driver.

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.

This reverts commit 0ebe112d09.
Most block devices have only one hwpart. Multiple hwparts only found used
by eMMC devices in u-boot. The mmc driver do blk_dselect_hwpart() at the
beginning of mmc_bread() which causes block cache being invalidated too
frequently and makes block cache useless.
So it's not a good idea to put blkcache_invalidate() in the common
functions. It should be called inside mmc_select_hwpart().
