[PATCH 0/2] ARM: dts: sun8i: r40: Add deinterlace node

[Jernej Skrabec]

These two patches add support for deinterlace core found on R40. It's
compatible to H3 one, so only DT node is needed.

Please take a look.

Best regards,
Jernej

[PATCH 1/2] dt-bindings: media: Add Allwinner R40 deinterlace compatible

[Jernej Skrabec]

Allwinner R40 SoC also contains deinterlace core, compatible to H3.

Add compatible string for it.

[PATCH 2/2] ARM: dts: sun8i: r40: Add deinterlace node

[Jernej Skrabec]

R40 contains deinterlace core compatible to that in H3. One peculiarity
is that RAM gate is shared with CSI1. User manual states it's separate
but that's not true. Shared gate was verified with BSP Linux code check
and with runtime tests (CPU crashed if CSI1 gate was not ungated).
