81015221a2 media: i2c: imx219: take lock in imx219_enum_mbus_code/frame_size
These two functions did not take the imx219->mutex lock, but
imx219_get_format_code checks that a lock is taken, so it issues
a warning:

1ed36ecd14 media: i2c: imx219: Selection compliance fixes
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.

[reword commit message, use macros for pixel offsets]

37bb22ed9c media: i2c: imx219: simplify getting state container
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.

ca45448a56 media: i2c: imx219: Fix power sequence
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.
