[PATCH v3 0/4] media: rockchip: Add rkvdec2 driver

[Detlev Casanova]

Add a rkvdec2 driver for newer video decoder found on rk3588 based SoC.

It is also found on other hardware like the RK356x, but not tested yet,
so it will be added later.

Support for yuv 4:2:2 and 10 bits streams will also be added later, when the
https://lore.kernel.org/linux-media/20240618194647.742037-1-jonas@kwiboo.se
patch set is merged.

The support for IOMMU will be added later as preliminary tests show that
the current rockchip iommu driver fails to allocate pages for the video
decoder iommu.

See the second commit message for more details.

Changes since v2:
- doc: Disable resets and sram for other platforms, add maxItems for
  clocks
- Fix h264 spec equation number in comment
- Remove superfluous status field in dtsi
- Add TODO item for IOMMU

Changes since v1:
- Add support for RCB in SRAM
- Move bindings to rockchip,vdec.yaml
- Add resets bindings
- Add second core and enable them from dtsi file
- Only expose one video device to userspace (but don't support multicore yet)
- Share CABAC table with rkvdec
- Fix iowrite32 call and add preliminary support for arm
- Remove unused code
- Improve registers naming and code style
- Remove DMA_ATTR_ALLOC_SINGLE_PAGES flag
