Changes since v2:
- Stephan: Rebased on v5.16-rc1
- Stephan: Fixed 3/4 commit message title
Changes since v1:
- Rob: Instead of documenting and fixing the use of the clock-lanes
property, remove it, since it is is not programmable and
therefore shouldn't be exposed in the DT.
Robert Foss (4):
media: camss: csiphy: Move to hardcode CSI Clock Lane number

2.32.0
QCOM ISPs do not support having a programmable CSI Clock Lane number.
In order to accurately reflect this, the different CSIPHY HW versions
need to have their own register layer for computing lane masks.

The clock-lanes property is not programmable by the hardware,
and as such it should not be exposed in the dt-binding.
