[PATCH v2 2/3] dt-bindings: clock: Add YAML schemas for the QCOM Camera clock bindings.
From: Taniya Das
Date: Tue Oct 13 2020 - 13:12:25 EST
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.
