We should probably make the final number GPIO_ACTIVE_LOW instead of 1.
You'll probably need to add this to the top:
#include <dt-bindings/gpio/gpio.h>
> + linux,code = <116>; /* KEY_POWER */
I believe you can just use KEY_POWER instead of 116 now, though you might need:
#include <dt-bindings/input/input.h>
See "tegra124-venice2.dts".

Similar here. Use #defines directly.

What happened to "powered-while-suspended"?

Actually, this won't work without the vdd-supply (unless you've got
dummy regulators enabled, which is non-ideal). I know I suggested
that maybe adc was ready to go into the device tree, but seeing the
missing buck makes me think we should wait.
I also notice that the adc is a little broken on ToT. I'll try to
submit another patch to fix.
For when you put this back in: you also are missing the status="okay" line...

Thanks for sending! My stuffy is mostly nits, so I think we're in
pretty good shape...
BTW: how much of the above have you tested? I don't think you tested
the ADC, but hopefully you tested the backlight / watchdog? Did you
test the SPI flash?
