The wave5 codec is a stateful encoder/decoder.
It is found on the JH7100 SoC.

The driver currently supports V4L2_PIX_FMT_HEVC, V4L2_PIX_FMT_H264.

This driver has so far been tested on pre-silicon FPGA and on the beta BeagleV
board which uses the StarFive JH7100 beta SoC.

Testing on FPGA shows it working fine, though the FPGA uses polled interrupts
and copied buffers between the host and it's on board RAM.

Testing on BeagleV shows buffer corruption that is currently attributed to a
known silicon issue in the SoC that makes the cache coherent interconnect not
so coherent.
This can likely be solved when the riscv non-coherent dma support lands and
provide optional v4l2 non-contiguous allocator, though it remains to be seen
whether support non-coherent use cases will be useful in real world hw.

Until we can test and resolve any issues on final silicon (due 2H 2021)
this driver should remain in staging.

We currently tested only the decoder.
Testing the encoder is currently impossible because of the BeagleV buffer problems,
That will need to be tested once we have fixed beaglev buffer problems.

For what it's worth; I think this is also the video decoder block on
the SigmaStar SSD201/SSD202D (32bit ARM..) that have some limited
support in mainline.

Cheers,
