[PATCH v3 0/9] Qualcomm video decoder/encoder driver

From: Stanimir Varbanov
Date: Mon Nov 07 2016 - 12:42:13 EST

Hi,

Here is v3 of the Venus v4l2 video encoder/decoder driver.

The changes since v2 are:
- return queued buffers on stream_on error.
- changed name of the driver vidc -> venus and reflect that in
querycap.
- fix video_device::release to point to video_device_release.
- tried to implement correctly g_selection for decoder and encoder.
- added Venus HFI 3xx basic support, to able to reuse driver on
msm8996.
- extend DT binding with reg-names and interrupt-names.
- parse DT IRQ and MEM resources by name.
- merge hfi_core,hfi_inst in venus_core and venus_inst structures.
- killed hfi_pkt_ops struct and use functions.
- various cleanups.

The output of v4l2-compliance looks like:
