Hello, This patch series improves the simple pipeline handler to support scaling (in the generic sense, this can be binning/skipping or real scaling) on the camera sensor in addition to the converter. This is useful on platforms that don't have a converter, but also on platforms where the SoC camera pipeline has limitations on resolution and/or bandwidth. Patches 1/5 and 2/5 are small drive-by improvements, patches 3/5 and 4/5 prepare for sensor scaling support with some code refactoring, and patch 5/5 then performs the bulk of the work, with an explanation of the heuristics used to configure scaling.
