[libcamera-devel] [PATCH v4 00/10] Raspberry Pi: Conversion to media controller

[Naushir Patuck]

Hi,

Version 4 of this series picks up a few more commits and changes:

- Patch 3/10 from Laurent added to use scoped enums for BayerFormat::Packing.
- Patch 4/10 adds formats::R10_CSI2P (10-bit mono packed) format. This can be
merged with 2/10 if folks think that is more appropriate.
- In 6/10 I've made the conversion table search success/failure return path
consistent with the rest of the file.
- I've moved the patch to setup h/v flips ahead of the other changes in 7/10.
This reduces code churn and avoids making the MC changes in parts of the code
that will eventually be deleted.
- In 8/10, reverted back to using the BayerFormat conversion table instead of
using a local one.
- In 8/10  merged the packing considations that were previously in a spearate
commit to reduce code churn in this series.
- In 8/10 added a new helper mbusCodeToPixelFormat() to replace the old mbusCodeToBayerFormat().
This reduces the number of overall lookups needed for our conversions, and also 
accounts for packing options.

Given the changes to 8/10, I've removed all existing tags for folk to have a re-review of
that change.

Thanks,
Naush
