Signed-off-by: Sandy Huang Signed-off-by: Heiko Stuebner Reviewed-by: Sean Paul Reviewed-by: Mark Yao --- Changes in v7: 1. forget to delete rockchip_rgb_driver and delete it. Changes in v6: 1. Update according to Heiko Stuebner' implemention, rgb output is part of vop's feature, should not register as a independent driver. Changes in v5: 1. add SPDX-License-Identifier tag Changes in v4: 1. add support px30; Changes in v3: 1. update for rgb-mode move to panel node. Changes in v2: 1. add error log when probe failed; 2. update name_to_output_mode() according to sean's suggest; 3.
