I think there is a rule that says the compatible string to be the same as the schema filename. Should I then also rename the schema file and also the binding IDs header? Like qcom,sm8550-tcsr.yaml and qcom,sm8550-tcsr.h ? > > > + > > + reg: > > + maxItems: 1 > > + > > + '#clock-cells': > > + const: 1 > > + > > + '#reset-cells': > > + const: 1 > > + > > Your clocks are fed by cxo.

Right, will document the clocks property as well and describe the clock as xo-board. > > Regards, > Bjorn > > > +required: > > + - compatible > > + > > +additionalProperties: false > > + > > +examples: > > + - | > > + clock-controller@1fc0000 { > > + compatible = "qcom,sm8550-tcsrcc"; > > + reg = <0x1fc0000 0x30000>; > > + #clock-cells = <1>; > > + #reset-cells = <1>; > > + }; > > + > > +... > > diff --git a/include/dt-bindings/clock/qcom,sm8550-tcsrcc.h b/include/dt-bindings/clock/qcom,sm8550-tcsrcc.h > > new file mode 100644 > > index 000000000000..091cb76f953a > > --- /dev/null > > +++ b/include/dt-bindings/clock/qcom,sm8550-tcsrcc.h > > @@ -0,0 +1,18 @@ > > +/* SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) */ > > +/* > > + * Copyright (c) 2022, The Linux Foundation.
