[PATCH V3 0/2] drm/panel: Add Samsung AMS495QA01 Panel

[Chris Morgan]

From: Chris Morgan <macromorgan at hotmail.com>

Add the Samsung AMS495QA01 panel as found on the Anbernic RG503. This
panel uses DSI to receive video signals, but 3-wire SPI to receive
command signals.

Changes since V2:
 - Added 50hz mode at request of userspace devs.
 - Renamed "dupa" to panel name. Good catch Maya.
 - Added Maya's Signed-off-by.
 - Removed check for max backlight, since it is already done by
   backlight_device_set_brightness.
 - Fixed minor formatting issues on devicetree binding documentation
   and added port to provided example.

Changes since V1:
 - Removed errant reference to backlight in documentation. This is an
   OLED panel.
 - Made elvss regulator optional. In my case its hard wired and not
   controllable.
 - Added "prepared" enum to track panel status to prevent unbalanced
   regulator enable/disable.
