For Spring I was asked to use GPIO_ACTIVE_* - here that would mean
s/0/GPIO_ACTIVE_HIGH/ IIUC and if necessary
#include <dt-bindings/gpio/gpio.h> before the .dtsi #include.
A modified version of your patch for Snow, rebased onto my cleanups, can
be found on my spring-next branch.

Nit: panel-simple seems backwards in English language, and given that
simple-panel would be referring to the implementation, I used just
"panel" for Spring.

FWIW this depends on auo,b133htn01 getting added to Documentation and
panel-simple, which I think hasn't happened yet?
