Changes in v4: - New Changes in v5: - Address review comments and move backlight functions to drm_panel.c (Douglas) - Create and register DP AUX backlight if there is no backlight specified in the device tree and panel has the DP AUX channel. (Douglas) - The new drm_panel_dp_aux_backlight() will do the drm_edp_backlight_supported() check.
