Code cleanup Note, these patches are dependent on below: 1] https://patchwork.kernel.org/project/linux-media/patch/20240416193319.778192-27-sakari.ailus@xxxxxxxxxxxxxxx/ 2] https://patchwork.kernel.org/project/linux-media/patch/20240416193319.778192-26-sakari.ailus@xxxxxxxxxxxxxxx/ v2->v3 - Fixed review commments from Laurent - Included RB tags from Laurent - Dropped patch "media: i2c: ov5645: Enable runtime PM after v4l2_async_register_subdev()" - Fixed checkpatch issues (ie used --max-line-length=80) RFC->v2 - Dropped setting of VC using routes - Defaulted the native format to MEDIA_BUS_FMT_SBGGR8_1X8 - Fixed ov5645_enum_frame_size and ov5645_enum_mbus_code for internal image pad RFC patch, Link: https://lore.kernel.org/all/20240904210719.52466-1-prabhakar.mahadev-lad.rj@xxxxxxxxxxxxxx/ Test logs: ==================================== root@smarc-rzg2l:~# media-ctl -p ...... -
