2021-04-06media: i2c: imx219: Balance runtime PM use-countLad Prabhakar
Move incrementing/decrementing runtime PM count to imx219_start_streaming()/imx219_stop_streaming() functions respectively. This fixes an issue of unbalanced runtime PM count in resume callback error path where streaming is stopped and runtime PM count is left unbalanced.

2020-12-02media: i2c: imx219: Selection compliance fixesHans Verkuil
To comply with the intended usage of the V4L2 selection target when used to retrieve a sensor image properties, adjust the rectangles returned by the imx219 driver. The top/left crop coordinates of the TGT_CROP rectangle were set to (0, 0) instead of (8, 8) which is the offset from the larger physical pixel array rectangle. This was also a mismatch with the default values crop rectangle value, so this is corrected. Found with v4l2-compliance. While at it, add V4L2_SEL_TGT_CROP_BOUNDS support: CROP_DEFAULT and CROP_BOUNDS have the same size as the non-active pixels are not readable using the selection API. Found with v4l2-compliance.

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.

2020-03-12media: i2c: imx219: Fix power sequenceLad Prabhakar
When supporting Rpi Camera v2 Module on the RZ/G2E, found the driver had some issues with rcar mipi-csi driver. The sensor never entered into LP-11 state. The powerup sequence in the datasheet[1] shows the sensor entering into LP-11 in streaming mode, so to fix this issue transitions are performed from "streaming -> standby" in the probe() after power up. With this commit the sensor is able to enter LP-11 mode during power up, as expected by some CSI-2 controllers.
