Also enum_mbus_code needs to be updated. The mbus code also has priority in mode selection, thus only the modes for the selected mbus code should considered in set_fmt. -- Regards, Sakari Ailus

The Bayer GRBG10 mode used for earlier modes 3280x2460 and 1640x1232 isn't the mode output by the sensor for the 3264x2448 and 1632x1224 modes. Switch from MEDIA_BUS_FMT_SGRBG10_1X10 to MEDIA_BUS_FMT_SBGGR10_1X10 for 3264x2448 & 1632x1224 modes. Signed-off-by: Robert Foss <robert.foss@linaro.org> --- This patch is sent out after Dongchun Zhu clarified the Bayer modes used by different sensor configuration in the below thread. https://lkml.org/lkml/2020/11/24/335 drivers/media/i2c/ov8856.c | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) -- 2.27.0
