(This series resumes [1].)
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 2nd patch adds
helper functions to do just that.
Patch 1: documents qcom,msm8939-camss DT bindings
Patch 2: adds helper for VFE VBIF settings
Patch 3: adds CAMSS_8x39 version in CAMSS driver
Patch 4: adds camss and cci in msm8939.dtsi
Changes compared to [1]:
- Move bindings patch to the beginning
- Make the order of {reg, clock, interrupt} items the same as in 8916 +
append additional items
- Drop R-b tags from bindings and dts patches as order of items was
changed
