The Powkiddy RGB30 device is similar to the Anbernic RGxx3 series,
however there are several differences which require deleting nodes in
order to properly define the hardware. This was deemed unacceptable
for the RK2023, so instead create a common include file for the

Improve the panel's ability to restore from suspend by holding the
panel in suspend after unprepare.

For devices like the Anbernic RG351M and RG351P the panel is wired to
an always on regulator. When the device suspends and wakes up, there
are some slight artifacts on the screen that go away over time. If

The driver shutdown is duplicate as it calls drm_unprepare and

Fix a few bugs and clean up no longer needed code on the Elida KD35T133
DSI panel, as used in devices such as the Odroid Go Advance and the

The rk2023-panel is similar to the rg353p-panel but has slightly
different timings so it needs a new string.
