This series adds support for JPEG encoding via the VPU block
present in Rockchip platforms. Currently, support for RK3288
and RK3399 is included.
Please, see the previous versions of this cover letter for
more information.

v5:
- Make coefficients 2-byte wide, to support 8-bit and 16-bit
precision coefficient. Also, add a 'precision' field, to
allow the user to specifiy the coefficient precision.
- Minor style changes as requested by Hans.
- Get rid of all the unused leftover code.
- Move driver to staging. The driver will support video encoding,
via the request API. So let's use staging until the
controls are stabilized.
v4:
- Change luma and chroma array controls, with a compound
control, as suggested by Paul.
v3:
- Refactor driver to allow a more elegant integration with
other codec modes (h264 decoding, jpeg decoding, etc).
Each variant can now be encoders, decoders or both.
- Register driver in the media controller framework,
in preparation for the Request API.
- Set values for JPEG quantization controls in the core, as suggested
by Tomasz and Hans.
- Move pm_runtime_get/put to run/done, reducing power consumption.
This was possible thanks to Miouyouyou, who pointed out the power
domains missing [1].
- Use bulk clock API for simpler code.
v2:
- Add devicetree binding documentation and devicetree changes
- Add documentation to added pixel format and controls
- Address Hans' review comments
- Get rid of unused running_ctx field
- Fix wrong planar pixel format depths
- Other minor changes for v4l2-compliance
- Drop .crop support, we will add support for the
selector API later, if needed.
