Does this linear brightness -> PWM duty cycle mapping lead to linear
relationship between brighntess level and subjective brightness on this HW?
I doubt it a bit...

Regulator node names shoule end with -regulator suffix. The same applies for

There's no such property. Delete this commented out line.

Re lcd0_rst_l:
It's a bit weird conceptually to reference from dtsi something that's only
declared in dts that includes the dtsi. Maybe move pinctrl-* properties
to dts &lcd, too...

I guess this prevents remote USB wakeup by USB devices. Like wakeup via USB
keyboard. Probably not a bad thing, though.

Does it make sense to enable this HW block by default, when it isn't used on
actual HW?

^^^ all of this wifi stuff is unused
Also wifi_pwren is not really useful on actual HW. W_VBAT is routed directly
to wifi chip, with wifi_pwren_h signal having no effect: (short via R9664)

That's a bit on the low side. The flash chip should work for all commands up to
80MHz https://megous.com/dl/tmp/b428ad9b85ac4633.png and SGM3157YC6 switch
for the FSPI-CLK should have high enough bandwidth, too.

GD25LQ128E supports quad I/O. Maybe try 4 if it will work.

Not sure about enabling UART for bluetooth, without having the bluetooth driver
hooked in, somehow. UART will by default pull TX signal high, which may cause
current leakage into gpio/uart pin of the bluetooth chip, if it's not powered up.
Maybe just remove this, until bluetooth is figured out...
kind regards,
