In the linux/drivers/video/fbdev/mxc/mxc_hdmi.c file is a function named mxc_hdmi_disp_init() where a hardcoded hdmi color mapping is set. setting->if_fmt = IPU_PIX_FMT_RGB24; This is not neccessary. The setting is already available in setting->if_fmt. Just delete it. it is made already available by the following functions and can be found on the following locations: linux/drivers/video/fbdev/mxc/mxc_ipuv3_fb.c mxcfb_option_setup() pdata->interface_pix_fmt = IPU_PIX_FMT_RGB24; linux/drivers/video/fbdev/mxc/mxc_ipuv3_fb.c mxcfb_dispdrv_init() setting.if_fmt = plat_data->interface_pix_fmt; |
