[v4,0/6] Add Rockchip VPU JPEG encoder

Message

Ezequiel Garcia Aug. 31, 2018, 3:41 p.m. UTC

This series adds support for JPEG encoding via the VPU block
present in Rockchip platforms. Currently, support for RK3288
and RK3399 is included.

This v4 patchset changes quantization luma and chroma array controls,
and instead introduces a compound control, V4L2_CID_JPEG_QUANTIZATION
for userspace to specify the luma and chroma quantization tables,
via a struct.

Rest of the changes are the same as v3.

This series does not depend on the Request API, since there are
some encoder uses that doesn't require it. So, if there are no
more comments, I'd like to merge this sooner than later.

Total: 48, Succeeded: 48, Failed: 0, Warnings: 0

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.
