Since, rgb24 and bgr24 reverse the byte numbers
/* rgb24 */
ipu_dc_map_clear(priv, IPU_DC_MAP_RGB24);
ipu_dc_map_config(priv, IPU_DC_MAP_RGB24, 0, 7, 0xff); /* blue */
ipu_dc_map_config(priv, IPU_DC_MAP_RGB24, 1, 15, 0xff); /* green */
ipu_dc_map_config(priv, IPU_DC_MAP_RGB24, 2, 23, 0xff); /* red */
/* bgr24 */
ipu_dc_map_clear(priv, IPU_DC_MAP_BGR24);
ipu_dc_map_config(priv, IPU_DC_MAP_BGR24, 2, 7, 0xff); /* red */

Shouldn't rgb666 and bgr666 do the same?
Currently we have,
/* bgr666 */
ipu_dc_map_clear(priv, IPU_DC_MAP_BGR666);
ipu_dc_map_config(priv, IPU_DC_MAP_BGR666, 0, 5, 0xfc); /* blue */
ipu_dc_map_config(priv, IPU_DC_MAP_BGR666, 1, 11, 0xfc); /*
green */
ipu_dc_map_config(priv, IPU_DC_MAP_BGR666, 2, 17, 0xfc); /* red */
Where I'd expect to see
/* bgr666 */
ipu_dc_map_clear(priv, IPU_DC_MAP_BGR666);
ipu_dc_map_config(priv, IPU_DC_MAP_BGR666, 0, 17, 0xfc); /* blue */
ipu_dc_map_config(priv, IPU_DC_MAP_BGR666, 1, 11, 0xfc); /*
green */
ipu_dc_map_config(priv, IPU_DC_MAP_BGR666, 2, 5, 0xfc); /* red */
So, it looks like you are adding a duplicate of bgr666 because bgr666 is
wrong.
Also, I'd prefer to keep the entries in 0,1,2 byte number order(blue,
green, red,
assuming byte 0 is always blue) so that duplicates are easier to spot.
Not related to this patch, but the comments on gbr24 appear wrong as well.
/* gbr24 */
ipu_dc_map_clear(priv, IPU_DC_MAP_GBR24);
ipu_dc_map_config(priv, IPU_DC_MAP_GBR24, 2, 15, 0xff); /* green */
ipu_dc_map_config(priv, IPU_DC_MAP_GBR24, 1, 7, 0xff); /* blue */
ipu_dc_map_config(priv, IPU_DC_MAP_GBR24, 0, 23, 0xff); /* red */
Should be
/* brg24 */
ipu_dc_map_clear(priv, IPU_DC_MAP_BRG24);
ipu_dc_map_config(priv, IPU_DC_MAP_BRG24, 0, 23, 0xff); /* blue*/
ipu_dc_map_config(priv, IPU_DC_MAP_BRG24, 1, 7, 0xff); /* green */
ipu_dc_map_config(priv, IPU_DC_MAP_BRG24, 2, 15, 0xff); /* red */
Of course, my understanding may be totally wrong. If so, please show me
the light!
