The way this is used in the code makes me suspect this should
be named reset-gpios. What is the name of the pin on the
panel?

It also appears you should tag this as active low so in that case
write that in the description "always tag with GPIO_ACTIVE_LOW"
(and alter the code in the driver to match the inversion)

Hm the name of this supply makes me think the display controller is
actually named pp1800. Is this correct?

Don't use ordinal flags in examples.

examples:
  - |
    #include <dt-bindings/gpio/gpio.h>
(...)
    reset-gpios = <&gpio4 11 GPIO_ACTIVE_LOW>;

Yours,
