[PATCH 0/8] media: sunxi: Add DE2 rotate driver

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Some of Allwinner SoCs like A83T and A64 SoCs contain DE2 rotate core
which can flip image horizontal and vertical and rotate it in 90 deg.
steps. It support a lot of output formats, but a bit less capture
formats. All YUV input formats get converted to yuv420p, while RGB
formats are preserved.

Patches 1-2 fix few issues with DE2 clocks.

Patches 3-4 fix register range of DE2 clocks (it would overlap with
rotate driver)

Patches 5-8 provide binding, implement driver and add nodes.
