[PATCH v2 0/8] Qualcomm video decoder/encoder driver

[Stanimir Varbanov]

Changes since v1:
  - s/ENOTSUPP/EINVAL in vidc_set_color_format()
  - use video_device_alloc
  - fill struct device pointer in vb2_queue_init instead of .setup_queue
  - fill device_caps in struct video_device instead of .vidioc_querycap
  - fill colorspace, ycbcr_enc, quantization and xfer_func only when type
    is V4L2_BUF_TYPE_VIDEO_OUTPUT_MPLANE
  - delete rproc_boot|shutdown wrappers in core.c
  - delete unused list_head in struct vidc_core
  - delete mem.c|h and inline the function where they were used
  - delete int_bufs.c|h files and move the functions in helpers.c, also
    cleanup the code by removing buffer reuse mechanism
  - inline INIT_VIDC_LIST macro
  - rename queue to other_queue in .start_streaming for encoder and
    decoder
  - renamed vidc_buf_descs -> vidc_get_bufreq
  - optimize instance checks in vidc_open
  - moved resources structure in core.c and delete resources.c|h
  - delete streamon and streamoff flags

The previous v1 can be found at [1].
