+ROHM BD71837 Power Management Integrated Circuit clock bindings
+
+This is a part of device tree bindings of ROHM BD71837 multi-function
+device. See generic BD71837 MFD bindings at:
+ Documentation/devicetree/bindings/mfd/rohm,bd71837-pmic.txt
+
+BD71837 contains one 32,768 KHz clock output which can be enabled and
+disabled via i2c.
+
+Following properties should be present in main device node of the MFD chip.
+
+Required properties:
+- clock-frequency : Should be 32768
+- #clock-cells : Should be 0
+
+Optional properties:
+- clock-output-names : Should contain name for output clock.
+
+Example:
+
+/* MFD node */
+
+pmic: pmic@4b {
+ compatible = "rohm,bd71837";
+ /* ... */
+ #clock-cells = <0>;
+ clock-frequency = <32768>;
+ /* ... */
+};
+
+/* Clock consumer node */
+
+foo@0 {
+ compatible = "bar,foo";
+ /* ... */
+ clock-names = "my-clock";
+ clocks = <&pmic>;
+};
