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 v4:
- set GAMMA_OUT to the real 25 instead of the 28 with 3 spares (Dafna)
- start RKISP_Vxx enum with 10 for RKISP_V10 to make output
easier and also allow userspace to differentiate between old (= 0)
and newer driver variants (Dafna, Laurent)
changes since v3:
- add patch fixing the original histogram size comment
- make comments in uapi more verbose (Hans)
- fix wording in admin guide (Hans)
- document version <-> soc in uapi as well (easier for people) (Dafna)
changes since v2:
- actually zero the correct sizes for u16 values (hist-bins)
(kernel-test-robot)
changes since v1:
- drop duplicate isp_ver storage, hw_revision is enough (Dafna)
- document multiple maximum sizes in uapi (Hans)
- document usage of hw_revision field (Hans)
- zero fields transmitted to userspace before adding data (Hans)
- 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
