[libcamera-devel] [PATCH v3 0/3] rkisp1: add an initial support to different hw revision

[Dafna Hirschfeld]

In kernel v5.11 the rkisp1 uapi had changed to support
different hardware versions. See [1].
Currently only version 10 is supported, therefore the IPA
should fail on 'init' if the revision is not 10.
In the future we want to add support for version V12.
See revisions documentation at [2].

Changes from v1:
- compilation fix in patch 3 that I forgot to update in first version
- typo fixes
- in patch 2, if 'configure' of the rkisp1 IPA fails return -EINVAL
- in patch 3, if hw revision is not supported, return -ENODEV

Changes from v2:
- in patch 1: add doxygen documentation for the new function hwRevision
- in patch 2: small typo fix
- in patch 3:
* the revision check is moved from the function 'configure' to the function 'init'.
* remove uapi header update and support for v10 since it is already done in a different patchset
