68852f3241 spi: cadence-qspi: Correct flash reset function name
In cadence_spi_probe, cadence_qspi_versal_flash_reset() is called to reset
the flash device. Looks like there is a mistake in previous series of
patches where it is defined as cadence_spi_versal_flash_reset() but
called as cadence_qspi_versal_flash_reset. Since there is a weak function
defined with the same name this issue was not caught.

Fix the issue by renaming cadence_spi_versal_flash_reset as
cadence_qspi_versal_flash_reset().

3f351cd358 cpu: microblaze: add error handling in microblaze_cpu_get_desc()
Check snprintf() return value for errors.

Make microblaze_cpu_get_desc() directly return snprintf() error code if
ret < 0. Otherwise, if the return value is greater than or equal to size,
the resulting string is truncated, so return -ENOSPC.

b7e0750d88 zynq: Convert arm twd timer to DM driver
Move arm twd timer driver from zynq to generic location.

DM timer drivers are designed differently to original driver. Timer is
counting up and not down.
Information about clock rates are find out in timer_pre_probe() that's
why there is no need to get any additional information from DT in the
driver itself (only register offset).

f127a58e05 firmware: ti_sci: Remove inline keyword from functions
The inline hint is not needed here, the compiler will do the right thing
based on if we are compiling for speed or for code size. In this case the
inline causes this function to be placed inside each callsite which is
not the right thing to do for either speed nor size. There is no
performance benefit to this due to the larger function size reducing
cache locality, but there is a huge size penalty. Remove inline keyword.

0ddabb6830 arm: dts: qcom: Sync pinctrl DT nodes with Linux bindings
Currently for all Qcom SoCs/boards there are separate compatibles for
GPIO and pinctrl. But this is inconsistent with official (upstream) Linux
bindings which requires only a single compatible "qcom,<SoC name>-pinctrl"
and there is no such compatible property as "qcom,tlmm-<SoC name>".

So fix this inconsistency for Qcom SoCs in order to comply with upstream
DT bindings. This is done via removing compatibles from "msm_gpio" driver
and via binding to "msm_gpio" driver from pinctrl driver in case
"gpio-controller" property is specified for pinctrl node.

Subpage write support for freescale eLBC NAND controller driver is

So remove NAND_NO_SUBPAGE_WRITE flag from the fsl_elbc_nand.c driver. This
partially revert commit cb04c77234 ("nand/fsl: add NAND_NO_SUBPAGE_WRITE
to eLBC and IFC drivers"), only eLBC driver part.

With this change U-Boot with default settings can read from NAND UBIFS
image created on Linux with Linux default settings. Prior this change
U-Boot was unable to read from NAND UBIFS images created with Linux default
settings due to differnet UBI geometry.

Linux kernel fsl_elbc_nand.c driver also does not set NAND_NO_SUBPAGE_WRITE
flag and has implemented subpage write support.

007f1d1473 mtd: nand: samsung: Retrieve ECC requirements from extended
Upstream linux commit 8fc82d456e40a0.

On some nand controllers with hw-ecc the controller code wants to know
the ecc strength and size and having these as 0, 0 is not accepted.

Specifying these in devicetree is possible but undesirable as the nand
may be different in different production runs of the same board, so it
is better to get this info from the nand id where possible.

This commit adds code to read the ecc strength and size from the nand
for Samsung extended-id nands. This code is based on the info for the 5th
id byte in the datasheets for the following Samsung nands: K9GAG08U0E,
K9GAG08U0F, K9GAG08X0D, K9GBG08U0A, K9GBG08U0B. These all use these bits
in the exact same way.

This is the control FDT used by U-Boot.

When booting an OS we may obtain a different device tree and want to
modify it. Add some initial support for this into the ofnode API.

Note that we don't permit aliases in this other device tree, since the
of_access implementation maintains a list of aliases collected at
start-up. Also, we don't need aliases to do fixups in the other FDT. So
make sure that flat tree and live tree processing are consistent in this
area.

2349ecffec mmc: Do not send status of send_status is false
Commit 44645f87de ("mmc: Fix mmc_switch excessive timeout") introduced
a side effect where CMD13 SEND_STATUS is issued in case mmc_wait_dat0()
does not return -ENOSYS and $send_status is not set. This happens on all
hardware which does implement .mmc_wait_dat0 callback, e.g. i.MX8M .

This leads to lengthy timeout before booting OS in case of eMMC in one
of the HS200/HS400 modes, since the card cannot respond to CMD13 while
downgrading from HS200/HS400 to regular HS mode.

Fix this by adding the missing conditional.

ca514d0267 misc: atsha204a: Don't check for error when waking up the device
The device ignores any levels or transitions on the SCL pin when the device
is idle, asleep or during waking up.

Linux kernel driver for atsha204a (atmel-sha204a.ko) also ignores return
value from i2c wakeup send command, see:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/crypto/atmel-i2c.c?h=v5.19#n174

And also userspace Turris libatsha204 library ignores return value from
wakeup send command, see:
https://gitlab.nic.cz/turris/libatsha204/-/blob/v29.2/src/libatsha204/layer_ni2c.c#L75-76

U-Boot driver should do same thing.

Fixes waking up ATSHA204 on Turris 1.x boards.

019090647c arm64: a37xx: pinctrl: Improve description for pinmux command
In more cases group name consist of function name followed by function
number. So if function name is just prefix of group name, show group name.

So in 'pinmux status -a' command output would be visible also extended
function number, which is useful for debugging.

7a1c071173 arm64: a37xx: pinctrl: Fix definitions for MPP pins 20-22
All 3 MPP pins (20, 21 and 22) can be configured individually and also can
be configured to GPIO functions. Fix definitions for these MPP pins in
existing pin groups. After this change GPIO function can be enabled just
for one of these 3 pins.
