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.

Laurent Pinchart (5):
  libcamera: pipeline: simple: Improve debug message on config failure
  libcamera: pipeline: simple: Document the pipeline traversal algorithm
  libcamera: pipeline: simple: Factor out format test to separate
    function
  libcamera: pipeline: simple: Store sensor resolution in configuration
  libcamera: pipeline: simple: Support scaling on the sensor
