Hey, This series adds a driver for the ST VGXY61 camera sensor. This camera sensor is using the i2c bus for control and the csi-2 bus for data. These commits introduce the MEDIA_BUS_FMT_Y16_1X16 as a media bus format (1/5), reserve 16 user controls for the driver (2/5), add a uapi header file to declare a control for the hdr mode (3/5), dt bindings (3/5), and finally the driver (5/5). Tested on DragonBoard 410c and on Raspberry Pi 4. Unfortunately, I was not able to do the freely configurable frame size as advised by Laurent, and I'm stuck. I tried to mimic the ov5693 driver as it seems to work mostly the same but was not successful. I managed to implement the get_selection to set the sensor crop, and set the set_format call to the same frame size. By doing that my captured frame has black lines appearing if I don't use the sensor native resolution, and seem to have issues with matching the sensor internal frame size and the one I want to display (as lines appear wider than they should be). If anyone has an example driver for this please tell me. Any help is appreciated. I hope this fixed frame sizes will be ok, and I could come back to it later once I figure it out.
