From: Chris Morgan <macromorgan@xxxxxxxxxxx> 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@xxxxxxxxx/ 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.
