[PATCH v2 0/2] Fix the rkisp1 userspace API for later IP versions

[Heiko Stuebner]

This NEEDs to go into 5.11 while we can still adapt the uapi
during its RC-cycle.


When looking into supporting the rkisp1 of the px30 I noticed that
some fields got bigger in the uapi, caused by bigger number of samples
for example for histograms or gamma values.

The rkisp1 was destaged with 5.11-rc1 so we have still time during
the 5.11 cycle to fix that without big hassles.

This was discussed previously in a mail [0] and a rfc series [1]
and this two-part series now splits out the important parts that
really should become part of a 5.11-rc and thus the final 5.11.

changes since v1:
- drop duplicate isp_ver storage, hw_revision is enough
- document multiple maximum sizes in uapi
- document usage of hw_revision field
- zero fields transmitted to userspace before adding data
- use _V10 field sizes when filling fields, as there is only v10 for now

changes since rfc:
- move rkisp1_version enum into uapo
- show version in media-api hw_revision
- introduce constants for versions and make max use the biggest
