This series adds CAMSS support for MSM8939.
It's mostly identical to MSM8916, except for some clocks
and an additional CSI.

To fix black stripes across sensor output, and garbage in
CSID TPG output, 2 VFE VBIF register settings are needed.
So the 1st patch adds helper functions to do just that.

Patch 1: adds helper for VFE VBIF settings
Patch 2: adds CAMSS_8x39 version in CAMSS driver
Patch 3: documents qcom,msm8939-camss DT bindings
Patch 4: adds camss and cci in msm8939.dtsi

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade
