[PATCH v9 6/7] dt-bindings: clock: Document qcom,apcs binding

From: Georgi Djakov
Date: Thu Sep 21 2017 - 12:51:07 EST


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.

+Qualcomm APCS Clock Controller Binding
+--------------------------------------
+The APCS hardware block provides a combined mux and half-integer divider
+functionality. It is used for a main CPU clock mux on MSM8916 platforms.
+
+Required properties :
+- compatible : shall contain only one of the following:
+
+ "qcom,msm8916-apcs-clk"
+
+- clocks : shall be the phandle to the main input CPU PLL clock
+
+- #clock-cells : must be set to <0>
+
+Example:
+
+ apcs: mailbox@b011000 {
+ compatible = "qcom,msm8916-apcs-kpss-global";
+ reg = <0xb011000 0x1000>;
+ #mbox-cells = <1>;
+
+ apcs_clk: apcs_clk {
+ compatible = "qcom,msm8916-apcs-clk";
+ clocks = <&a53pll>;
+ #clock-cells = <0>;
+ };
+ };
