drm: Print pretty names for pixel formats
Rather than just printing the pixel format as a hex number, decode the fourcc into human readable form, and also decode the LE vs. BE flag. Keep printing the raw hex number too in case it contains non-printable characters. Some examples what the new drm_get_format_name() produces: DRM_FORMAT_XRGB8888: "XR24 little-endian (0x34325258)" DRM_FORMAT_YUYV: "YUYV little-endian (0x56595559)" DRM_FORMAT_RGB565|DRM_FORMAT_BIG_ENDIAN: "RG16 big-endian (0xb6314752)" Unprintable characters: "D??? big-endian (0xff7f0244)" v2: Fix patch author Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
