Hi,

This patch set adds support for fast and high quality colour denoise processing to the Raspberry Pi pipeline.  As mentioned in the relevant commit message texts, there are accompanying firmware and kernel changes that must be build into the image for colour denoise to work.

Patches 1/5 and 2/5 start by reworking stream configuration handling.  This is because we need a 1/4 resolution analysis image to be available for our "fast" colour denoise implementation.  Additionally, this will only work on YUV420 format images for now.

Thanks,
Naush
