The semantics of pfn_valid() is to check presence of the memory map for a
PFN and not whether a PFN is covered by the linear map. The memory map
may be present for NOMAP memory regions, but they won't be mapped in the
linear mapping. Accessing such regions via __va() when they are
memremap()'ed will cause a crash.
On v5.4.y the crash happens on qemu-arm with UEFI [1]:

On kernels v5.10.y and newer the same crash won't reproduce on ARM because
commit b10d6bca8720 ("arch, drivers: replace for_each_membock() with
for_each_mem_range()") changed the way memory regions are registered in
the resource tree, but that merely covers up the problem.
On ARM64 memory resources registered in yet another way and there the
issue of wrong usage of pfn_valid() to ensure availability of the linear
map is also covered.
Implement arch_memremap_can_ram_remap() on ARM and ARM64 to prevent access
to NOMAP regions via the linear mapping in memremap().

This reverts commit 0dc23d1a8e17, which caused another regression

The correct spelling for the property is gpios. Otherwise, the regulator
will neither reserve nor control any GPIOs. Thus, any SD/MMC card which

The Samsung pinctrl drivers depend on OF_GPIO, which is part of GPIOLIB.
ARMv7 Exynos platform selects GPIOLIB and Samsung pinctrl drivers. ARMv8
Exynos selects only the latter leading to possible wrong configuration
on ARMv8 build:
WARNING: unmet direct dependencies detected for PINCTRL_EXYNOS
Depends on [n]: PINCTRL [=y] && OF_GPIO [=n] && (ARCH_EXYNOS [=y] || ARCH_S5PV210 || COMPILE_TEST [=y])
Selected by [y]:
- ARCH_EXYNOS [=y]
Always select the GPIOLIB from the Samsung pinctrl drivers to fix the
issue. This requires removing of OF_GPIO dependency (to avoid recursive
dependency), so add dependency on OF for COMPILE_TEST cases.

The Gemini defconfig needs to be updated due to DSA driver
Kconfig changes in the v5.18 merge window:
CONFIG_NET_DSA_REALTEK_SMI is now behind
CONFIG_NET_DSA_REALTEK and the desired DSA switch need
to be selected explicitly with
CONFIG_NET_DSA_REALTEK_RTL8366RB.
Take this opportunity to update some other minor config
options:
- CONFIG_MARVELL_PHY moved around because of Kconfig
changes.
- CONFIG_SENSORS_DRIVETEMP should be selected since is
regulates the system critical alert temperature on
some devices, which is nice if it is handled even
if initramfs or root fails to mount.

The pinout of the OMAP35 and DM37 variants of the SOM-LV are the
same, but the macros which define the pinmuxing are different
between OMAP3530 and DM3730. The pinmuxing was correct for
for the DM3730, but wrong for the OMAP3530. Since the boot loader
was correctly pin-muxing the pins, this was not obvious. As the
bootloader not guaranteed to pinmux all the pins any more, this
causes an issue, so the pinmux needs to be moved from a common
file to their respective board files.

The bootloader for the AM3517 has previously done much of the pin
muxing, but as the bootloader is moving more and more to a model
based on the device tree, it may no longer automatically mux the
pins, so it is necessary to add the pinmuxing to the Linux device
trees so the respective peripherals can remain functional.

When adding support for TI magadc (Magnetic Stripe Reader and ADC), the
MFD driver common to the touchscreen and the ADC got updated to ease the
insertion of a new DT node for the ADC, with its own compatible, clocks,
etc. Commit 235a96e92c16 ("mfd: ti_am335x_tscadc: Don't search the tree
for our clock") removed one compatible specific information which was
the clock name, because the clock was looked up from scratch in the DT
while this hardware block was only fed by a single clock, already
defined and properly filled in the DT.
Problem is, this change was only validated with an am437x-based board,
where the clocks are effectively correctly defined and referenced. But
on am33xx, the ADC clock is also correctly defined but is not referenced
with a clock phandle as it ought to be.
The touchscreen bindings clearly state that the clocks/clock-names
properties are mandatory, but they have been forgotten in one DTSI. This
was probably not noticed in the first place because of the clock
actually existing and the clk_get() call going through all the tree
anyway.
Add the missing clock phandles in the am33xx touchscreen description.

Support GPIO controllers without pin-ranges"). For SPI controllers
available on SAMA5D4 and SAMA5D3 some of the pins are defined in
SoC specific dtsi on behalf of pinctrl-0. Adding extra pinctrl phandles
on board specific dts also on behalf of pinctrl-0 overwrite the pinctrl-0
phandle specified in SoC specific dtsi. Thus add the board specific
pinctrl to pinctrl-1.

The at91sam9g20ek has no software controllable regulators, only some fixed
discrete regulators, but they are there and currently the wm8731 driver
does try to use them. Show the supplies in the DT and map them for the
wm8731 so things start up cleanly.

The MCLK of the WM8731 on the AT91SAM9G20-EK board is connected to the
PCK0 output of the SoC and is expected to be set to 12MHz. Previously
this was mapped using pre-common clock API calls in the audio machine
driver but the conversion to the common clock framework broke that so
describe things in the DT instead.

The impedance of the QSPI PCB lines on the sama7g5ek is 50 Ohms.
Align the output impedance of the QSPI0 HSIOs by setting a medium drive
strength which corresponds to an impedance of 56 Ohms when VDD is in the
3.0V - 3.6V range. The high drive strength setting corresponds to an
output impedance of 42 Ohms on the QSPI0 HSIOs.

Flexcom3 is used as board console serial. There are no pull-ups on these
lines on the board. This means that if a cable is not connected (that has
pull-ups included), stray characters could appear on the console as the
floating pins voltage levels are interpreted as incoming characters.
To avoid this problem, enable the internal pull-ups on these lines.

We currently are getting the following warning after a system suspend:
Powerdomain (vpe_pwrdm) didn't enter target state 0
Looks like this is because the STANDBYMODE bit for SMART_IDLE should
not be used. The TRM "Table 12-348. VPE_SYSCONFIG" says that the value
for SMART_IDLE is "0x2: Same behavior as bit-field value of 0x1". But
if the SMART_IDLE value is used, PM_VPE_PWRSTST LASTPOWERSTATEENTERED
bits always show value of 3.
Let's fix the issue by dropping SMART_IDLE for vpe. And let's also add
the missing the powerdomain for vpe.

On a custom carrier board with a i.MX6Q Apalis SoM, the sgtl5000 codec
on the SoM is often not detected and the following error message is
seen when the sgtl5000 driver tries to read the ID register:
sgtl5000 1-000a: Error reading chip id -6
The reason for the error is that the MCLK clock is not provided
early enough.
Fix the problem by describing the MCLK pinctrl inside the codec
node instead of placing it inside the audmux pinctrl group.
With this change applied the sgtl5000 is always detected on every boot.
