[PATCH v2 1/4] backlight: hx8357: Make use of device properties

2024-02-01 Thread Andy Shevchenko
Convert the module to be property provider agnostic and allow
it to be used on non-OF platforms.

Include mod_devicetable.h explicitly to replace the dropped of.h
which included mod_devicetable.h indirectly.
