- Video support:
CONFIG_VIDEO_SED13806
Enable Epson SED13806 driver. This driver supports 8bpp
and 16bpp modes defined by CONFIG_VIDEO_SED13806_8BPP
or CONFIG_VIDEO_SED13806_16BPP
CONFIG_FSL_DIU_FB
Enable the Freescale DIU video driver. Reference boards for
SOCs that have a DIU should define this macro to enable DIU
