For some reason I remembered ExynosAutoV9 sending them together but I
was wrong, will seperate in the future.

Well, if we have both an interrupt and gpio access, why not provide
both? According to the documentation, `Specifying both properties is
allowed.`

There is a front RGB led, but IIRC that is accessed through the S2MU004
MFD using I2C. There's also a rear "ktd2692" flash, which might or
might not be controllable using that, will need to check that one.

Was wondering about this too, but a quick grep showed that
EXYNOS_PIN_FUNC_EINT was not used in any dts, and in fact only used in
"drivers/pinctrl/samsung/pinctrl-exynos.c". The one that was used in
dts/dtsis is EXYNOS_PIN_FUNC_F.

Just found "exynos_gpio_config_macros.dtsi" in the downstream code not
long ago, I guess you are right!

Good catch! Will add it!

They are real pins (as in they do something inside the SoC for sure),
but don't seem to be used for much. Some dtsis show "AP_JTAG_TRST_N"
being on etc0-0. I'm guessing these are some kind of debug pins? Have
you seen anything about them on the 850?

These are the two clocks, and it's definitely wrong swapped, as it
breaks switching baudrates, but PCLK does in fact have PERI_BUS_USER as
it's parent. while EXT_UCLK has PERI_UART0_USER as parent. Not sure
what is up with it here but it works fine this way but not the other
way around.

They do in fact work on my phone ;)
One thing I noticed is that if I send a poweroff command and hold down
the power key, it will stay powered on until I release it. I guess
that's just how it's wired up.
Sometimes, very rarely a reboot does act weird though: Every once in a
while, a reboot turns the phone off, then the bootloader starts
outputting on UART before it cuts off my connection to UART by
resetting the MUIC, and the phone never powers on again by itself
after. (like.. bootloader starts then powers the phone off even before
the display would come on?) I should check the bootloader logs saved to
a last_kmsg buffer the next time this happens, but this looks like more
of a bootloader issue rather than this being wrong.
