This panel uses DSI to receive video signals, but 3-wire SPI to receive command signals using DBI. Changes since V5: - Reverted dt binding documentation name back to samsung,ams495qa01.yaml. - Removed no longer needed of_graph.h header file. - Added backlight as a dependency. Changes since V4: - Renamed driver from the panel model to the panel IC controller per DRM team. - Added a drm_of helper function of drm_of_get_dsi_bus() to handle finding and populating the DSI node when the DSI node is not the parent of the DSI controlled display. - Converted the documented commands to constants to make it more readable. - Reset GPIO is now required and documented as GPIO_ACTIVE_LOW. - Removed "prepared" logic from panel. 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.
