media: common: Add v4l2_find_nearest_size_conditional()

2025-05-06T11:06:30Z

v4l2_find_nearest_size() returns a mode from sensor driver's mode list that is a best match width and height wise for the sensor. Some drivers have different set of available modes depending on the number of lanes. While this could be handled within a driver by providing different lists of modes, provide a helper v4l2_find_nearest_size_conditional() to ignore modes that aren't available. Also use size_t for the array index and remove extra commas while at it. Signed-off-by: Sakari Ailus Signed-off-by: Hans Verkuil

media: renesas: vsp1: Expose color space through the DRM API

2025-05-02T08:16:44Z

Now that the VSP1 driver supports color spaces, expose them through the API used by the DU driver. This allows configuring the YCbCr encoding and quantization used by each plane, ensuring correct color rendering.

media: rc: reduce useless padding in struct rc_dev etc

2025-03-04T14:56:11Z

Reorder the fields in these structs so that we waste less space due to padding. pahole shows that lirc_fh is 8 bytes smaller, and rc_dev is 32 bytes smaller. Signed-off-by: Sean Young Signed-off-by: Hans Verkuil

'struct tunertype', 'struct tuner_range' and 'struct tuner_params' are not modified in this driver. Constifying these structures moves some data to a read-only section, so increase overall security.
