Hi all,

This is v3 of the wdr preparation series. I hope it is ready to go. Most
of the patches have 2 rby tags. I repost because patch 6 and 7 were
reworked. Patch 6 contains the error message when queuing parameter
buffers fails. The functionality to check for available parameter types
was pulled into linux 6.17. I therefore reduced the error message in
patch 6 to a generic "Failed to queue parameter buffer" as this might
still be valuable information even though it is not expected to happen
regularly. Patch 7 was simplified as result of the reviews and therefore
misses the rby tags.

Best regards,
Stefan

--- Old cover letter below.

This v2 fixes a few minor errors found in v1. The main reason for the
repost is to create a basis for the upcoming WDR series.

The rest of the text here is unmodified (the changelogs are in the
patches).

This patch series does a bit of preparatory work for the upcoming WDR
support. The patches are a mix of topics but as they are all quite
small, I thought that a small series might be the best fit.

Patches 1-3 are tiny improvements in gen-debug-controls that ease the
day to day work.

Patches 4 and 7 add a bit of debug logging.

Patches 5-6 fix a bug in the rkisp1 parameters handling.

Patches 8-9 add support for exposure compensation in rkisp1.

I hope you all like it :-)

Best regards,
Stefan
