+ROHM BD71837 Power Management Integrated Circuit clock bindings
+
+BD71837 clock node should be sub node of the BD71837 MFD node.
+See BD71837 MFD bindings at
+Documentation/devicetree/bindings/mfd/rohm,bd71837-pmic.txt
+
+Required properties:
+- compatible : Should be "rohm,bd71837-clk"
+- clock-frequency : Should be 32768
+- #clock-cells : Should be 0
+
+Optional properties:
+- clock-output-names : Should contain name for output clock.
+ Name "bd71837-32k-out" is used if this is not given.
+
+
+Example:
+
+pmic: bd71837@4b {
+ compatible = "rohm,bd71837";
+ #address-cells = <1>;
+ #size-cells = <0>;
+ reg = <0x4b>;
+ interrupt-parent = <&gpio1>;
+ interrupts = <29 GPIO_ACTIVE_LOW>;
+ interrupt-names = "irq";
+ #interrupt-cells = <1>;
+ interrupt-controller;
+
+ /* Clock node */
+ clk: bd71837-32k-out {
+ compatible = "rohm,bd71837-clk";
+ #clock-cells = <0>;
+ clock-frequency = <32768>;
+ clock-output-names = "bd71837-32k-out";
+ };
+};
