Commit b6664ba42f ("s390, kexec_file: drop arch_kexec_mem_walk()")
changed kexec_add_buffer() to skip searching for a memory location if
kexec_buf.mem is already set, and use the address that is there.
In powerpc code we reuse a kexec_buf variable for loading both the
kernel and the initramfs by resetting some of the fields between those
uses, but not mem. This causes kexec_add_buffer() to try to load the
kernel at the same address where initramfs will be loaded, which is
naturally rejected:
# kexec -s -l --initrd initramfs vmlinuz
kexec_file_load failed: Invalid argument
Setting the mem field before every call to kexec_add_buffer() fixes
this regression.

Amlogic's vendor kernel has an explicit #define for the "DMC" register
range on Meson8m2 while there's no such #define for Meson8. However, the
canvas and memory controller registers on Meson8 are all expressed as
"0x6000 + actual offset", while Meson8m2 uses "DMC + actual offset".
Thus it's safe to assume that the DMC bus exists on both SoCs even
though the registers inside are slightly different.

This is similar to commit e6186820a7 ("arm64: dts: rockchip: Arch
counter doesn't tick in system suspend"). Specifically on the rk3288
it can be seen that the timer stops ticking in suspend if we end up
running through the "osc_disable" path in rk3288_slp_mode_set(). In
that path the 24 MHz clock will turn off and the timer stops.
To test this, I ran this on a Chrome OS filesystem:
before=$(date); \
suspend_stress_test -c1 --suspend_min=30 --suspend_max=31; \
echo ${before}; date
...and I found that unless I plug in a device that requests USB wakeup
to be active that the two calls to "date" would show that fewer than
30 seconds passed.
NOTE: deep suspend (where the 24 MHz clock gets disabled) isn't
supported yet on upstream Linux so this was tested on a downstream
kernel.

We can now use the "gpio-line-names" property to provide the names for
all the pins on a board. Let's use this to provide the names for all
the pins on rk3288-veyron-minnie.
In general the names here come straight from the schematic. That
means even if the schematic name is weird / doesn't have consistent
naming conventions / has typos I still haven't made any changes.
The exception here is for two pins: the recovery switch and the write
protect detection pin. These two pins need to have standardized names
since crossystem (a Chrome OS tool) uses these names to query the
pins. In downstream kernels crossystem used an out-of-tree driver to
do this but it has now been moved to the gpiod API and needs the
standardized names.
It's expected that other rk3288-veyron boards will get similar patches
shortly.
NOTE: I have sorted the "gpio" section to be next to the "pinctrl"
section since it seems to logically make the most sense there.
