I'm a bit confused. "qcom/venus-4.4/venus.mdt" is the Sony signed FW? This patch can't be merged unless there is a corresponding firmware available in linux-firmware. Is the current 4.2 firmware in linux-firmware signed by Qualcomm? Can they provided 4.4 firmware as well? I have no idea how this works for the venus driver, but I hope Stanimir does.

As such, providing means for specifying the firmware name in DT would be a very reasonable thing, and in line with how we handle this in other subsystems (using the firmware-name property, containing the full relative path).

Add the SDM660 DT compatible and its resource structure, also including support for the Venus pmdomains, in order to support the Venus block in SDM630, SDM636, SDM660 and SDA variants. This SoC features Venus 4.4 (HFI3XX), with one vcodec used for both encoding and decoding, switched on through two GDSCs. The core clock for this Venus chip is powered by the RPM VDD_CX power domain.
