In other words, I think you should add the two clock properties to the apcs node, rather than adding a subnode. I also think you can make the mailbox driver implement the clock given the 8916 compatible. > + compatible = "qcom,msm8916-apcs-clk"; > + clocks = <&a53pll>; > + #clock-cells = <0>; > + }; > + }; Regards, Bjorn -- To unsubscribe from this list: send the line "unsubscribe linux-arm-msm" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Add device-tree binding documentation for the Qualcom APCS clock controller. This clock controller is a mux and half-integer divider and provides the clock for the application CPU.
