[PATCH v4 17/39] board: dragonboard410c: upstream DT compat
Caleb Connolly
caleb.connolly at linaro.org
Thu Feb 15 21:52:35 CET 2024
Use the root compatible strings from upstream Linux, add missing
'#clock-cells' property to the gcc node.
Adjust some of the msm8916/apq8016 drivers to use the correct upstream
compatible properties and DT bindings.
This prepares us to switch to upstream DT in a future patch.
