[PATCH 0/6] H6 Cedrus support

[PATCH 0/6] H6 Cedrus support

[Jernej Skrabec]

This patch series adds basic support for H6 VPU. VPU itself has some new
features like 10-bit HEVC decoding, support for AFBC output format when
decoding HEVC and IOMMU. However, none of that is currently implemented.

Please take a look.

Best regards,
Jernej

[PATCH 1/6] dt-bindings: media: cedrus: Add H6 compatible

[Jernej Skrabec]

This adds a compatible for H6. H6 VPU supports 10-bit HEVC decoding and
additional AFBC output format for HEVC.

[PATCH 2/6] media: cedrus: Add a quirk for not setting DMA offset

[Jernej Skrabec]

H6 VPU doesn't work if DMA offset is set.

Add a quirk for it.

[PATCH 5/6] arm64: dts: allwinner: h6: Add support for the SRAM C1 section

[Jernej Skrabec]

Add a node for H6 SRAM C1 section.

Manual calls it VE SRAM, but for consistency with older SoCs, SRAM C1
name is used.

Looks like the patch adding SRAM support made it through but this one
didn't. It looks ready to be picked up though.
