The hardware have evolved mostly w.r.t higher number of power domains as well as multiple clock sources. It has support for new codec(apv), when compared to prior generation. >From previous version of this series, the kaanapali binding patch(#1/8) and the compatible patch(#8/8) have been dropped. The discussion for this is captured here [1]. The series introducs buffer calculation and power sequence for vpu4. It prepares for vpu4 when kaanapali is enabled after the binding discussion is concluded. [1] https://lore.kernel.org/linux-media/fdf4c469-d276-4f64-b13d-5266cca7235c@oss.qualcomm.com/ Please review and share your comments. Following are the compliance and functional validation reports executed on kaanapali(vpu4). For the series to be functional on vpu4, patch #8 from version of the series need to be explicitly included. v4l2-compliance report, for decoder followed by encoder, including streaming tests:

This is under debug with rpmh module owner to conclude if it to be fixed differently.
