2021-04-06media: v4l: fwnode: Rename v4l2_async_register_subdev_sensor_commonSakari Ailus
Rename v4l2_async_register_subdev_sensor_common as v4l2_async_register_subdev_sensor. This is a part of the effort to make the long names present in V4L2 fwnode and async frameworks shorter.

2021-02-06media: ov8856: Configure sensor for GRBG Bayer for all modesRobert Foss
The previously added modes 3264x2448 & 1632x1224 are actually configuring the sensor for BGGR mode, this is an issue since the mode that is exposed through V4L incorrectly is set as GRBG. This patch fixes the issue by moving the output crop window of internal sensor ISP uses by one row, which means that the Bayer pattern of the output is changed. row 1: B G B G B G ... row 2: G R G R G R ... row 3: B G B G B G ... ... row 2: G R G R G R ... row 3: B G B G B G ... ...

2020-11-16media: i2c: ov8856: simplify getting state containerKrzysztof Kozlowski
The pointer to 'struct v4l2_subdev' is stored in drvdata via v4l2_i2c_subdev_init() so there is no point of a dance like: struct i2c_client *client = to_i2c_client(struct device *dev) struct v4l2_subdev *sd = i2c_get_clientdata(client); This allows to remove local variable 'client' and few pointer dereferences.
