Hi everyone! Here is patchset which adds support for Hantro G2 core found in Allwinner H6 SoC. It is slightly older core, so it needs few quirks to be implemented: 1. It uses slightly different register layout in some cases. However, those differences are small, so it makes sense only to add quirks. 2. It doesn't use ring buffer for bitstream as newer variants. 3. It needs double buffering to be enabled in order to work correctly. 4. postproc must be enabled at the end of the job. It seems that core has some issues with latching register values if postproc registers are set at the beginning of the job legacy_regs quirk could be split into 3, like legacy_regs, ring_buffer and late_postproc, but I didn't see the need for that. I examined vendor sources at [1] and it suggests that legacy_regs implies no ring buffer. It's also unclear if core supports HEVC decoding or not. This can be implemented later. VP9 10-bit decoding support is mentioned in manual, but it doesn't work at the moment. This will be addressed later. Please take a look.
