dt-bindings: clock: Add YAML schemas for the QCOM Camera clock bindings.
Browse files Browse the repository at this point in the history 
The Camera Subsystem clock provider have a bunch of generic properties
that are needed in a device tree. Add a YAML schemas for those.

Add clock ids for camera clocks which are required to bring the camera
subsystem out of reset.
