[PATCH 00/12] media: rkvdec: Add support for VDPU381 and VDPU383

[Detlev Casanova]

These variants are found respectively in the RK3588 and RK3576 SoCs.
This patch only adds support for H264 and H265 in both variants.

As there is a considerable part of the code that can be shared with the
already supported rkvdec decoder driver, the support for these variants
is added here rather than writing a new driver.

This patch set uses the newly introduced EXT_SPS_RPS v4l2 control for
HEVC [1].
Therefore, a patched version of userpace tools is needed for HEVC
support (currently only added for GStreamer[2])

This patch set also depends on the preparation patch set sent earlier [3]
as well as the iommu restore fix [4] (already merged in linux-media) and
Nicolas Frattaroli's bitmap patch [5] to support setting registers that
uses upper 16 bits as masks.
