Add support for the following Raspberry Pi displays: - DFROBOT DRF0678 7in 800x480 TFT DSI capacitive touch - DFROBOT DRF0550 5in 800x480 TFT DSI capacitive touch Both have the following hardware: - FocalTech FT5406 10pt touch controller (with no interrupt) - Powertip PH800480T013-IDF02 compatible panel - Toshiba TC358762 compatible DSI to DBI bridge - ATTINY based regulator used for backlight controller and panel enable Support is added via a device-tree overlay. The touch controller is not yet supported as polling mode is needed. Signed-off-by: Tim Harvey <tharvey@gateworks.com> Signed-off-by: Shawn Guo <shawnguo@kernel.org>
