SIMPLE_PANEL currently only depends on PANEL && BACKLIGHT, but the code
makes references to dm_gpio_set_value and gpio_request_by_name. These
are defined in drivers/gpio/gpio-uclass.c, so a dependency on DM_GPIO
corrects these link errors:
aarch64-linux-gnu-ld.bfd: drivers/built-in.o: in function `simple_panel_set_backlight':
/home/kameliya/u-boot/drivers/video/simple_panel.c:42: undefined reference to `dm_gpio_set_value'

This PWM is used in rk3399-gru-bob and rk3399-gru-kevin to control
the display brightness. We can only change the duty cycle, so on
set_config() we just try to match the duty cycle that dividing duty_ns
by period_ns gives us. To disable, we set the duty cycle to zero while
keeping the old value for when we want to re-enable it.
The cros_ec_set_pwm_duty() function is taken from Depthcharge's
cros_ec_set_bl_pwm_duty() but modified to use the generic pwm type.
The driver itself is very loosely based on rk_pwm.c for the general pwm
driver structure.
The devicetree binding file is from Linux, before it was converted to
YAML at 5df5a577a6b4 ("dt-bindings: pwm: Convert google,cros-ec-pwm.txt
to YAML format") in their repo.

The PWM device provided by Chrome OS EC doesn't really support anything
other than setting a relative duty cycle. To support it as a backlight,
this patch makes the PWM period optional in the device tree and pretends
the valid brightness range is its period_ns.
Also adds a sandbox test for a PWM channel that has a fixed period,
checking that the resulting duty_cycle matches on a set_config() even if
the requested period_ns can't be set.

endpoint to find out if the endpoint is mipi/hdmi/lvds/edp/dp. The order
is different between rk3288, rk3399 vop little, rk3399 vop big.
A possible solution would be to make sure that the rk3288.dtsi and

to find the kind of endpoint by comparing the endpoint compatible value.

We had a problem detecting 8/16bit flash devices connected only via

[mtd: cfi_flash: Fix CFI flash driver for 8-bit bus support] finally
fixed this 8-bit bus support. But also broke some other boards using
this cfi driver. So this patch had to be reverted.
I spotted a different, simpler approach for this 8-bit bus support
on the barebox mailing list posted by
Oleksij Rempel <bug-track@fisher-privat.net>:
http://www.spinics.net/lists/u-boot-v2/msg14687.html
Here the commit text:
"
Many cfi chips support 16 and 8 bit modes. Most important
difference is use of so called "Q15/A-1" pin. In 16bit mode this
pin is used for data IO. In 8bit mode, it is an address input
which add one more least significant bit (LSB). In this case
we should shift all adresses by one:
For example 0xaa << 1 = 0x154
"
This patch now is a port of this barebox patch to U-Boot.
Along with the change w.r.t from barebox,
Some flash chips can support multiple bus widths, override the
interface width and limit it to the port width.

The code was trying to disable PCS auto-negotiation when a fixed-link node
is present and enable it otherwise. However, the PCS registers were being
written before the PCSSEL bit was set in the network configuration
register, and it appears that in this state, PCS register writes are
ignored. The result is that the intended change only took effect on the
second network operation that was performed, since at that time PCSSEL is
already enabled.
Fix the order of register writes so that PCS registers are only written to
after the PCS is enabled.

This feature was dropped from U-Boot some time ago:
f12f96cfaf (sf: Drop spl_flash_get_sw_write_prot")
However, we do need a way to see if a flash device is write-protected,
since if it is, it may not be possible to write to do (i.e. failing to
write is expected).
I am not sure of the correct layer to implement this, so this patch is a
stab at it. If spi-flash makes sense then I will add to the 'sf' also.
Re the points mentioned in the removal commit:
1) This kind of requirement can be achieved using existing
flash operations and flash locking API calls instead of
making a separate flash API.
Which uclass is this?
2) Technically there is no real hardware user for this API to
use in the source tree.
I do want coral (at least) to support this.
3) Having a flash operations API for simple register read bits
also make difficult to extend the flash operations.
This new patch only mentions write-protect being on or off, rather than
the actual mechanism.
4) Instead of touching generic code, it is possible to have
this functionality inside spinor operations in the form of
flash hooks or fixups for associated flash chips.
That sounds to me like what drivers are for. But we still need some sort
of API for it to be accessible.

The Intel GPIO binding allows GPIOs to be globally numbered, so that it
does not matter which GPIO bank is specified in the device tree. This is
convenient and avoid confusion since the banks do not have the same number
of GPIOs and the numbering is not sequential.
The GPIO uclass ensures that the device mentioned in the devicetree
binding is probed. It is fine for the driver to update gpio_desc to point
to a different driver, but this may not have been probed. If it has not
been, then it cannot be claimed since there is no uclass data.
We could handle this in the GPIO uclass but so far it is an unusual
situation so it is probably not worth the extra code. Handle this case in
the GPIO driver by probing the selected device if necessary.

At the moment nvme_read_completion_status() tries to invalidate a single

not cache line aligned.
The structure is dictated by hardware, and with 16 bytes is smaller than
any cache line we usually deal with. Also multiple entries need to be
consecutive in memory, so we can't pad them to cover a whole cache line.
As a consequence we can only always invalidate all of them - U-Boot just
uses two of them anyway. This is fine, as they are only ever read by the
CPU (apart from the initial zeroing), so they can't become dirty.
Make this obvious by always invalidating the whole array, regardless of
the entry number we are about to read.

With of-platdata we always have a dtv struct that holds the platform data
provided by the driver_info record. However, this struct can be empty if
there are no actual devicetree properties provided.
The upshot of empty platform data is that it will end up as a zero-size
member in the BSS section, which is fine. But if the driver specifies
plat_auto then it expects the correct amount of space to be allocated.
At present this does not happen, since device_bind() assumes that the
platform-data size will always be >0. As a result we end up not
allocating the space and just use the BSS region, overwriting whatever
other contents are present.
Fix this by removing the condition that platform data be non-empty, always
allocating space if requested.
This fixes a strange bug that has been lurking since of-platdata was
implemented. It has likely never been noticed since devices normally have
at least some devicetree properties, BSS is seldom used on SPL, the dtv
structs are normally at the end of bss and the overwriting only happens
if a driver changes its platform data.
It was discovered using sandbox_spl, which exercises more features than
a normal board might, and the critical global_data variable 'gd' happened
to be at the end of BSS.

Marvell Armada 3720 Functional Errata, Guidelines, and Restrictions
document describes in erratum 4.1 PCIe value of vendor ID (Ref #: 243):
The readback value of VEND_ID (RD0070000h [15:0]) is 1B4Bh, while it
should read 11ABh.
The firmware can write the correct value, 11ABh, through VEND_ID
(RD0076044h [15:0]).
Implement this workaround in U-Boot PCIe controller driver aardvark for
both PCI vendor id and PCI subsystem vendor id.
This change affects PCI vendor id of PCIe root bridge emulated by Linux
kernel. With this change Linux kernel reports correct vendor id 11AB.

The arrays `pbs_dq_mapping`, `div_ratio1to1` and `div_ratio2to1` have
different bounds declared in header files where these variables are also
defined from the ones declared in source files.
This causes the compiler to complain (when building with LTO):

CI managed to trigger this as an error when compiling with LTO for AXP.
Fix this by using values from the header files, which seem to be the

In arch/arm/mach-mvebu/dram.c we always include axp's xor.h for common
XOR definitions, regardless whether we compile for axp or a38x.
But the declaration of this function has a different signature in axp's
xor.h from the one used in a38x' implementation - one parameter is u64
instead of u32. This can result in wrong argument's being passed to that
function on a38x with no one the wiser.
I discovered this when building U-Boot for Turris Omnia with LTO. The
compiler complains about the different signatures being thrown into the
same linking process:
axp/xor.h:67:5: warning: type of ‘mv_xor_mem_init’ does not match
original declaration [-Wlto-type-mismatch]
67 | int mv_xor_mem_init(u32 chan, u32 start_ptr, u32 block_size,

a38x/xor.c:165:5: note: type mismatch in parameter 3
165 | int mv_xor_mem_init(u32 chan, u32 start_ptr, unsigned long long
| ^
a38x/xor.c:165:5: note: type ‘long long unsigned int’ should match
type ‘u32’
Fix this by changing the type of the block_size argument in the axp's
implementation and header file to the one used in a38x (and upstream
mv-ddr-marvell).

This syncs drivers/ddr/marvell/a38x/ with the master branch of repository
https://github.com/MarvellEmbeddedProcessors/mv-ddr-marvell.git up to the
commit 7c351731d196 ("Merge pull request #29 from pali/sync-a38x-uboot").
This patch was created by following steps:
1. Replace all a38x files in U-Boot tree by files from upstream github
Marvell mv-ddr-marvell repository.
2. Run following command to omit portions not relevant for a38x and ddr3:
files=drivers/ddr/marvell/a38x/*
sed 's/#if defined(CONFIG_ARMADA_38X) || defined(CONFIG_ARMADA_39X)/#ifdef TRUE/' -i $files
unifdef -m -UMV_DDR -UMV_DDR_ATF -UCONFIG_DDR4 -UCONFIG_APN806 \
-UCONFIG_MC_STATIC -UCONFIG_MC_STATIC_PRINT -UCONFIG_PHY_STATIC \
-UCONFIG_PHY_STATIC_PRINT -UCONFIG_CUSTOMER_BOARD_SUPPORT \
-UCONFIG_A3700 -UA3900 -UA80X0 -UA70X0 -DTRUE $files
3. Manually omit SPDX-License-Identifier changes from this patch as
upstream license in upstream github repository contains long license
texts and U-Boot is using just SPDX-License-Identifier.
After applying this patch, a38x ddr3 code in upstream Marvell github
repository and in U-Boot would be fully identical. So in future applying
above steps could be used to sync code again.
The only change in this patch is removal of dead code and some fixes with
include files.

The DSI phy can be turned on from the DSI digital interface in
the dphy_enable() function or from a dedicated DSI phy "wrapper"
in phy_ops->init() function. If the STM32MP1 case, the wrapper
is used then the dphy_enable() "warning" traces are not relevant.
This patch moves these "warning" traces to "debug" traces so
they are still available for DSI phy based on the digital
interface in debug logging mode, but not there in normal mode
for both cases.
Note: The related Linux kernel driver uses a "debug"
message too.

For the next request, the PANEL ofdata_to_platdata failed as the gpio
