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 V3:
- Updated documentation to add spi-peripheral-props.yaml per updates
made for similar devices. Note that I removed a "Reviewed-by" tag
from Rob Herring since this change probably needs to be confirmed.
- Added binding for RG503, since this device is now accepted with this
request: https://lore.kernel.org/linux-rockchip/166274831283.21181.6861718157177507544.b4-ty@sntech.de/
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.
