[PATCH v4 0/9] media: qcom: venus: add MSM8939 support

[Erikas Bitovtas <xerikasxx@gmail.com>]

This patch series adds support for Venus on MSM8939. It is mostly
similar to MSM8916 Venus, except it needs two additional cores to be
powered on before it can start decoding.

As per Dmitry's request, I am attaching Fluster results and
v4l2-compliance output. Fluster results were very inconsistent and
caused power collapse fails.

Changes in v4:
- Removed vcodec{0,1}_pmdomains and merged vcodec{0,1}_clks into
  vcodec_clks instead for MSM8939.
- Inlined video decoder and encoder device tree nodes in the driver and
  removed them from the binding.
- Kept vdec and venc methods for HFI v3 separate from HFI v1.
- {vdec,venc}_get() are now called as early as before, since it is no
  longer needed for us to attach power domains to dev_dec and dev_enc.
- Link to v3: https://patch.msgid.link/20260427-msm8939-venus-rfc-v3-0-288195bb7917@gmail.com

Changes in v3:
- Added missing vcodec1_clks to resource struct.
- Removed enc_nodename from resource struct since we include
  video-decoder now.
- Link to v2: https://patch.msgid.link/20260425-msm8939-venus-rfc-v2-0-f69e52b36207@gmail.com

Changes in v2:
- Enabled GDSCs during encoding as well.
- Merged vcodec{0,1}_pmdomains_num into vcodec_pmdomains_num.
- Reworded commit for marking GDSCs as hardware controlled. Same
  situation as in cdc59600bccf ("clk: qcom: gcc-msm8953: fix stuck venus0_core0 clock")
- Clarified the reason for missing firmware-name property in device
  tree.
- Clarified the reason for moving vdec_get and venc_get for later.
- Link to v1: https://patch.msgid.link/20260416-msm8939-venus-rfc-v1-0-a09fcf2c23df@gmail.com
