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

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.
