Subject: [PATCH 0/2] media: i2c: imx219: Fix regressions introduced by
 1x2/2x1 binning

This series fixes a regression introduced in commit 0af46fbc333d
("media: i2c: imx219: Calculate crop rectangle dynamically") that
started using vertical binning for 1920x1080 without binning
horizontally, causing the captured images to be stretched in one
dimension.

In a subsequent patch, simplify the binning mode calculation logic as
well. This is done separately, without a fixes tag, as it is cleaning up
code that was introduced much later to the regression commit, and
doesn't strictly require backporting.

Once Sakari's metadata series with binning controls [1] is merged, this
and other existing sensor drivers may be extended to support free
configuration of resolution, and give the userspace freedom to bin
pixels in only one dimension if required, of course, as long as it
doesn't cause regressions with exsiting userspace applications.
