4ddc91b32f clk: fixed-rate: Export driver parts for OF_PLATDATA_INST
We need to allow SoCs to create their own drivers for this so that they
can use their own of-platdata structs. To minimise code duplication,
export the driver operations and the ofdata_to_plat() setup function.

e86ad666d0 log: convert pr_*() to logging
In drivers we use a family of printing functions including pr_err() and
pr_cont(). CONFIG_LOGLEVEL is used to control which of these lead to output
via printf().

Our logging functions allow finer grained control of output. So replace
printf() by the matching logging functions. The usage of CONFIG_LOGLEVEL
remains unchanged.

a764c94128 usb: gadget: OS Feature Descriptors support
This is a proting patch from linux kernel: 37a3a533429e
("usb: gadget: OS Feature Descriptors support"), the original commit
log see below:

There is a custom (non-USB IF) extension to the USB standard:

http://msdn.microsoft.com/library/windows/hardware/gg463182

They grant permission to use the specification - there is
"Microsoft OS Descriptor Specification License Agreement"
under the link mentioned above, and its Section 2 "Grant
of License", letter (b) reads:

"Patent license. Microsoft hereby grants to You a nonexclusive,
royalty-free, nontransferable, worldwide license under Microsoft鈥檚
patents embodied solely within the Specification and that are owned
or licensable by Microsoft to make, use, import, offer to sell,
sell and distribute directly or indirectly to Your Licensees Your
Implementation. You may sublicense this patent license to Your
Licensees under the same terms and conditions."

The said extension is maintained by Microsoft for Microsoft.

Yet it is fairly common for various devices to use it, and a
popular proprietary operating system expects devices to provide
"OS descriptors", so Linux-based USB gadgets whishing to be able
to talk to a variety of operating systems should be able to provide
the "OS descriptors".

This patch adds optional support for gadgets whishing to expose
the so called "OS Feature Descriptors", that is "Extended Compatibility ID"
and "Extended Properties".

Hosts which do request "OS descriptors" from gadgets do so during
the enumeration phase and before the configuration is set with
SET_CONFIGURATION. What is more, those hosts never ask for configurations
at indices other than 0. Therefore, gadgets whishing to provide
"OS descriptors" must designate one configuration to be used with
this kind of hosts - this is what os_desc_config is added for in
struct usb_composite_dev. There is an additional advantage to it:
if a gadget provides "OS descriptors" and designates one configuration
to be used with such non-USB-compliant hosts it can invoke
"usb_add_config" in any order because the designated configuration
will be reported to be at index 0 anyway.

This patch also adds handling vendor-specific requests addressed
at device or interface and related to handling "OS descriptors"."

("usb: gadget: OS String support"), original commit log

The contents of the string is generated based on the qw_sign
array and b_vendor_code.

Interested gadgets need to set the cdev->use_os_string flag,
fill cdev->qw_sign with appropriate values and fill cdev->b_vendor_code
with a value of their choice.

This patch does not however implement responding to any vendor-specific

b7cfe32e18 smccc: fix sign bit expansion
Signed ARM_SMCCC_FAST_CALL value is shifted to 31'st bit. Then, it is expanded
to 64 bit value, which results in 1s in higher 32 bits.

This causes corrupted values in 64-bit SMC IDs and issues in buggy handlers of
32-bit calls.

We need to make ARM_SMCCC_FAST_CALL unsigned long, so it would work properly
on 32 bit architectures.

- Move the 'struct spi_flash' to column 1 so dtoc scans it
- Remove the #define when compiling dt-platdata.c
- Update the strange mtd_get/set_of_node() functions
- Use struct spi_nor in the drivers, so dtoc sees the correct struct

720fcb27e0 mtd: spinand: micron: identify SPI NAND device with Continuous Read mode
Add SPINAND_HAS_CR_FEAT_BIT flag to identify the SPI NAND device with
the Continuous Read mode.

Some of the Micron SPI NAND devices have the "Continuous Read" feature
enabled by default, which does not fit the subsystem needs.

In this mode, the READ CACHE command doesn't require the starting column
address. The device always output the data starting from the first
column of the cache register, and once the end of the cache register
reached, the data output continues through the next page. With the
continuous read mode, it is possible to read out the entire block using
a single READ command, and once the end of the block reached, the output
pins become High-Z state. However, during this mode the read command
doesn't output the OOB area.

Hence, we disable the feature at probe time.

7842749c35 linux/kconfig.h: create two- and three-argument versions of CONFIG_IS_ENABLED
This adds a bunch of preprocessor magic to extend the capabilities of
CONFIG_IS_ENABLED. The existing semantics of

  CONFIG_IS_ENABLED(FOO)

expanding to a 1 or 0 (depending on build context and the defined-ness
or not of the appropriate CONFIG_FOO/CONFIG_SPL_FOO/CONFIG_TPL_FOO)
are of course preserved. With this, one is also allowed a two-argument
form

  CONFIG_IS_ENABLED(FOO, (something))

which expands to something precisely when CONFIG_IS_ENABLED(FOO) would
expand to 1, and expands to nothing otherwise. It is, in other words,
completely equivalent to the three lines

  #if CONFIG_IS_ENABLED(FOO)
  something
  #endif

The second argument must be parenthesized in order to allow any
tokens, including a trailing comma, to appear - one use case for this
is precisely to make it a bit more ergonomic to build an array and
only include certain items depending on .config. That should increase
both readability and not least "git grep"ability.

A third variant is also introduced,

  CONFIG_IS_ENABLED(FOO, (xxx), (yyy))

which corresponds to

  #if CONFIG_IS_ENABLED(FOO)
  xxx
  #else
  yyy
  #endif

7d78a4547d linux/kconfig.h: remove unused helper macros
U-Boot does not have loadable modules, and nothing currently uses any
of the (CONFIG_)?IS_(BUILTIN|MODULE) macros - only
the (CONFIG_)?IS_ENABLED variants are ever used.

While I understand the desire to keep this somewhat synchronized with
linux, we've already departed by the introduction of the
CONFIG_IS_ENABLED extra logic, and deleting these makes the next patch
much simpler, since I won't have to duplicate a lot of logic for no
real gain (as there are no users).

b4f73886c4 linux/kconfig.h: simplify logic for choosing CONFIG_{SPL_, TPL_, }*
Instead of using the arg1_or_junk trick to pick between two choices,
with a bit of duplication between the branches (and most of the
CONFIG_TPL_BUILD case being redundant, as _IS_TPL is known to be
defined to 1 in that case), simply define a prefix that we inject
between CONFIG_ and the given config symbol.

This only requires one level of indirection (to get the
_CONFIG_PREFIX macro expanded before the token concatenation takes
place), and makes it easy to, say, introduce a CONFIG_HOSTTOOL_
prefix. [I would expect most HOSTTOOL_ symbols to just be def_bool y,
but it would allow us to clean up some of the ifdef HOSTCC mess in the
sources shared between U-Boot and host tools.]

1f1a0f3db3 compiler_types.h: Re-introduce CONFIG_OPTIMIZE_INLINING for U-Boot
In the Linux kernel, support for forcing inline functions to be made
inline, rather than allowing the compiler to make its own choice has
been removed.  With respect to performance, modern GCC (and Clang) do a
good job at deciding when to, or not to, inline code and there are no
run-time requirements in Linux anymore.

There is one downside to this, which is final binary size.  On average
in U-Boot removing this support grows SPL by almost 1 kilobyte.  But
there are cases where it shrinks the binary by making better inline
choices than we had forced.

Start by re-introducing CONFIG_OPTIMIZE_INLINING as a global which
essentially reverts 889b3c1245de ("compiler: remove CONFIG_OPTIMIZE_INLINING entirely")
from Linux.

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.

6b7ebff001 usb: dwc3: Add phy interface for dwc3_uboot
U-Boot has two different variants of dwc3 initializations,
- with dm variant gadget, so the respective dm driver would
  call the dwc3_init in core.
- with non-dm variant gadget, so the usage board file would
  call dwc3_uboot_init in core.

The driver probe would handle all respective gadget properties
including phy interface via phy_type property and then trigger
dwc3_init for dm-variant gadgets.

So, to support the phy interface for non-dm variant gadgets,
the better option is dwc3_uboot_init since there is no
dedicated controller for non-dm variant gadgets.

This patch support for adding phy interface like 8/16-bit UTMI+
code for dwc3_uboot.

This patch changes ERR_PTR/PTR_ERR to use CONFIG_ERR_PTR_OFFSET to map
errno values into a pointer region that cannot contain valid pointers.

IS_ERR and IS_ERR_OR_NULL have to be converted to use PTR_ERR, too,

8d94e184ff usb: udc: Introduce ->udc_set_speed() method
This patch was copied from kernel commit: 67fdfda4a99ed.

Sometimes, the gadget driver we want to run has max_speed lower than
what the UDC supports. In such situations, UDC might want to make sure
we don't try to connect on speeds not supported by the gadget
driver because that will just fail.

So here introduce a new optional ->udc_set_speed() method which can be
implemented by interested UDC drivers to achieve this purpose.

Any host while requesting for a device can request for its exclusive
access. If an exclusive permission is obtained then it is the host's
responsibility to release the device before the software entity on
the host completes its execution. Else any other host's request for
the device will be nacked. So add a command that releases all the
exclusive devices that is acquired by the current host. This should
be used with utmost care and can be called only at the end of the

1d7993d1d0 clk: Port Linux common clock framework [CCF] for imx6q to U-boot (tag: v5.1.12)
This patch brings the files from Linux kernel (linux-stable/linux-5.1.y
SHA1: 5752b50477da)to provide clocks support as it is used on the Linux
kernel with Common Clock Framework [CCF] setup.

The directory structure has been preserved. The ported code only supports
reading information from PLL, MUX, Divider, etc and enabling/disabling
the clocks USDHCx/ECSPIx depending on used bus. Moreover, it is agnostic
to the alias numbering as the information about the clock is read from the
device tree.

One needs to pay attention to the comments indicating necessary for U-Boot's
driver model changes.

If needed, the code can be extended to support the "set" part of the clock
management.

ffcc66e8fe dma: ti: add driver to K3 UDMA
The UDMA-P is intended to perform similar (but significantly upgraded) functions
as the packet-oriented DMA used on previous SoC devices. The UDMA-P module
supports the transmission and reception of various packet types.
The UDMA-P also supports acting as both a UTC and UDMA-C for its internal
channels. Channels in the UDMA-P can be configured to be either Packet-Based or
Third-Party channels on a channel by channel basis.

The initial driver supports:
- MEM_TO_MEM (TR mode)
- DEV_TO_MEM (Packet mode)
- MEM_TO_DEV (Packet mode)

432f66fe73 soc: ti: k3: add navss ringacc driver
The Ring Accelerator (RINGACC or RA) provides hardware acceleration to
enable straightforward passing of work between a producer and a consumer.
There is one RINGACC module per NAVSS on TI AM65x SoCs.

The RINGACC converts constant-address read and write accesses to equivalent
read or write accesses to a circular data structure in memory. The RINGACC
eliminates the need for each DMA controller which needs to access ring
elements from having to know the current state of the ring (base address,
current offset). The DMA controller performs a read or write access to a
specific address range (which maps to the source interface on the RINGACC)
and the RINGACC replaces the address for the transaction with a new address
which corresponds to the head or tail element of the ring (head for reads,
tail for writes). Since the RINGACC maintains the state, multiple DMA
controllers or channels are allowed to coherently share the same rings as
applicable. The RINGACC is able to place data which is destined towards
software into cached memory directly.

Supported ring modes:
 - Ring Mode
 - Messaging Mode
 - Credentials Mode
 - Queue Manager Mode

TI-SCI integration:

Texas Instrument's System Control Interface (TI-SCI) Message Protocol now
has control over Ringacc module resources management (RM) and Rings
configuration.

The Ringacc driver manages Rings allocation by itself now and requests
TI-SCI firmware to allocate and configure specific Rings only. It's done
this way because, Linux driver implements two stage Rings allocation and
configuration (allocate ring and configure ring) while TI-SCI Message
Protocol supports only one combined operation (allocate+configure).

In arch/sandbox/include/asm/types.h we have
Therefore for 32 bit Sandbox build BITS_PER_LONG turns out to be 32 as

This messes up the current logic of GENMASK macro due to mismatch b/w

Fix this by using CONFIG_SANDBOX_BITS_PER_LONG which is set to 64/32

4a5594fa20 mtd: Don't stop MTD partition creation when it fails on one device
MTD partition creation code is a bit tricky. It tries to figure out
when things have changed (either MTD dev list or mtdparts/mtdids vars)
and when that happens it first deletes all the partitions that had been
previously created and then creates the new ones based on the new
mtdparts/mtdids values.
But before deleting the old partitions, it ensures that none of the
currently registered parts are being used and bails out when that's
not the case. So, we end up in a situation where, if at least one MTD
dev has one of its partitions used by someone (UBI for instance), the
partitions update logic no longer works for other devs.

Rework the code to relax the logic and allow updates of MTD parts on
devices that are not being used (we still refuse to updates parts on
devices who have at least one of their partitions used by someone).

49c751603c time: Update mdelay() to delay in one large chunk
The current function delays in one millisecond at a time. This does not
work well on sandbox since it results in lots of calls to usleep(1000) in
a tight loop. This makes the sleep duration quite variable since each call
results in a sleep of *at least* 1000us, but possibly more. Depending on
how busy the machine is, the sleep time can change quite a bit.

We cannot fix this in general, but we can reduce the effect by doing a
single sleep. The multiplication works fine with an unsigned long argument
up until a sleep time of about 4m milliseconds. This is over an hour and
we can be sure that delays of that length are not useful.

Update the mdelay() function to call udelay() only once with the
calculated delay value.

81ea00838c efi_loader: PSCI reset and shutdown
When an operating system started via bootefi tries to reset or power off
this is done by calling the EFI runtime ResetSystem(). On most ARMv8 system
the actual reset relies on PSCI. Depending on whether the PSCI firmware
resides the hypervisor (EL2) or in the secure monitor (EL3) either an HVC
or an SMC command has to be issued.

The current implementation always uses SMC. This results in crashes on
systems where the PSCI firmware is implemented in the hypervisor, e.g.
qemu-arm64_defconfig.

The logic to decide which call is needed based on the device tree is
already implemented in the PSCI firmware driver. During the EFI runtime
the device driver model is not available. But we can minimize code
duplication by merging the EFI runtime reset and poweroff code with
the PSCI firmware driver.

As the same HVC/SMC problem is also evident for the ARMv8 do_poweroff
and reset_misc routines let's move them into the same code module.
