+Subject: [PATCH 01/17] libcamera: software_isp: Clarify SwStatsCpu::setWindow
+ use
+
+The window coordinates passed to SwStatsCpu::setWindow are confusing.
+Let's clarify what the coordinates should be.
+
+A source of confusion is that the specified window is relative to the
+processed area.  Debayering adjusts line pointers for its processed area
+and this is what's also passed to stats processing.  The window passed
+to SwStatsCpu::setWindow should either specify the size of the whole
+processed (not image) area, or its cropping in case the stats shouldn't
+be gathered over the whole processed area.  This patch should clarify
+this in the code.

+
+The window set by SwStatsCpu::setWindow is relative to the processed

+gathering stats from a wrong image area or in not gathering stats at

+
+Let's pass the correct y-coordinate to the stats processing methods.

+Subject: [PATCH 03/17] libcamera: software_isp: Check processed window size
+ alignment
+
+The window of the image that should be debayered must be aligned to the
+bayer pattern size.  This is already ensured for the window corner
+coordinates but not for the window sizes.
+
+We can either make the window sizes aligned similarly to how the window
+corner coordinates are aligned or reject an unaligned configuration.
+This patches chooses the latter as using a different window size than
+the requested output size could lead to artefacts.  Since such a
+situation is not expected to occur in correctly set up environments, the
+change should have no negative impact.

+Subject: [PATCH 12/17] ipa/simple: Add tuning file for IMX355
+
+64 at 10 bits. The value was guessed from known values for similar
+sensors and testing - on a Google Pixel 3a - suggest it's correct.
+
+Adding this tuning file is partly motivated in order to serve as
+example, as it's the first one for the simple IPA.
