Subject: kernel: add support for imx pxp
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=a9a872b9d4ccf0d79381d20e114742439606132f;p=openwrt%2Fstaging%2Fnbd.git

kernel: add support for imx pxp

This adds support for the i.MX Pixel Pipeline IP block
which is available on some imx6 flavours [1]

This allows to use hardware offloading for operations like:
- Colour conversion
- Scaling
- Rotation
