[PATCH v2 0/3] Rockchip RK3328 VDEC support

[PATCH v2 0/3] Rockchip RK3328 VDEC support

[Christopher Obbard]

This series adds VDEC support for the Rockchip RK3328 SoC which
uses the staging rkvdec driver.

Testing was performed using both v4l-compliance and (mainline) gstreamer
using the fluster framework:

    $ v4l2-compliance -m0
    v4l2-compliance 1.22.1, 64 bits, 64-bit time_t
    ...
    Grand Total for rkvdec device /dev/media0: 54, Succeeded: 54, Failed: 0, Warnings: 0


    $ python3 fluster.py run -j1 -ts JVT-AVC_V1 -d GStreamer-H.264-V4L2SL-Gst1.0
    ...
    Ran 111/135 tests successfully               in 392.885 secs


    $ python3 fluster.py run -j1 -ts VP9-TEST-VECTORS -d GStreamer-VP9-V4L2SL-Gst1.0
    ...
    Ran 206/303 tests successfully               in 1170.120 secs


Changes in v2:
 - Fix mistake in dt-binding compatible documentation
 - Remove unused reset nodes from devicetree
 - Improve some commit messages
 - Check all dts files against dtbs_check
 - Collect review tags on unchanged patches

[PATCH v2 2/3] arm64: dts: rockchip: Rename vdec_mmu node for RK3328

[Christopher Obbard]

All other rockchip devices which have vdec nodes do not
have an rk prefix. Remove the prefix from the (currently
unused) rkvdec_mmu node for consistency with other
devices.

[PATCH v2 3/3] arm64: dts: rockchip: Add vdec support for RK3328

[Christopher Obbard]

The RK3328 has an vdec device with dedicated iommu.
Describe the vdec device, the required power-domains
and enable the iommu in the devicetree.

This should be rather an enum with rk3228, so:
- enum
   - rockchip,rk3228-vdec
   - rockchip,rk3328-vdec
- const: rockchip,rk3399-vdec

Best regards,
Krzysztof

Thanks for your patience with reviewing the series. I sent v3 which 
should finally solve this now.

Cheers!
