[libcamera-devel] [PATCH 00/20] Raspberry Pi: Preliminary PiSP support

[Naushir Patuck]

Hi,

This (rather large) series introduces infrastructure needed for adding Raspberry
Pi 5 support into libcamera.  As some of you may be aware, Raspberry Pi 5 has
new in-house designed ISP (named PiSP) and Camera Front End (CFE) hardware
pipelines to handle camera and imaging tasks.

The patches in this series add some necessary functionality and algorithms
needed for the new PISP pipeline handler and IPA to function correctly.  The
actual pipeline handler and IPA code is not included in this series.  We are
waiting for the associated kernel drivers to be upstreamed before sending them
to this mailing list.  However, the code is available to inspect (particularly
to understand the context of some of these changes) at
https://github.com/raspberrypi/libcamera.

Finally, even though my name is listed as the author on most of the commits, the
following people also share authorship for this work:

David Plowman
Nick Hollinghurst
William Vinnicombe

Thanks,
Naush
