Subject: [PATCH v2 0/2] clk: qcom: Add GCC support for SM7150

Add the Global Clock Controller for SM7150.

Changes in v2:
- Dropped redundant "binding" in subject
- Fixed yamllint and dtschema errors
- Replaced additionalProperties with unevaluatedProperties
- Added Danila and David to maintainers
- Added Konrad Reviewed-by on patch 2
- Link to v1: https://lore.kernel.org/linux-clk/[email protected]/

If you started your work from the most recent bindings (e.g. sm8550) you
would have saved one iteration and one set of review...

Drop entire property, it's coming from gcc.yaml.

You did not base your work on any existing bindings upstream or
downstream? This should include original work copyrights...
