This patch series implements support for the entire camera subsystem
found in SDM630/636/660 and SDA variants, including CSIPHY 3-Phase,
CSID v5.0, ISPIF 3.0 (though it didn't need any adaptation) and
VFE 4.8.
One small note about VFE4.8, even if I wrote it in the commit that
adds support for it: I know, the VFE support here is split in
multiple files having the name of the actual VFE version that it is
targeting... but it didn't feel right to commonize the VFE 4.7 file
and make another one only for VFE4.8, when it's just about something
like 3 small differences.
That VFE 4.8 seems to be just a minor revision of VFE 4.7.
While at it, also fix a small issue when using two VFEs: only one
of them was being resetted (always VFE0) so, after the first usage
of VFE1, in case we leave it in a bad state, it would not properly
start again. Now... it's fine :)))
P.S.: SDM630/660's camss seems to be *very* similar to MSM8998, so
likely 90% of this series should be reusable on that one, too!
Tested on:
- Sony Xperia XA2 (IMX300 on CSI0/PHY0/VFE0, IMX219 on CSI2,PHY2,VFE1)
* VFE0/1 RDI only, as the VIDEO one does not work with SRGGB Bayer
formats yet. As far as I can see, that color format hasn't been
implemented yet in the video interface.
Changes in v2:
- Splitted out VFE 4.7 functions rename from the VFE 4.8 support commit
- Moved a commit so that sequentially picking patches from this series
still results in buildable code (heh, oops! sorry!)
- Fixed ispif reset commit (moved the fix for itfrom the wrong commit
to the right one: that was a "funny" overlook).
