+X-Powers AC100 Codec/RTC IC device tree bindings
+
+AC100 is a audio codec and RTC subsystem combo IC. The 2 parts are
+separated, including power supplies and interrupt lines, but share
+a common register address space and host interface.
+
+Required properties:
+- compatible: "x-powers,ac100"
+- reg: The I2C slave address or RSB hardware address for the chip
+- sub-nodes:
+  - codec
+    - compatible: "x-powers,ac100-codec"
+    - interrupt-parent: The parent interrupt controller
+    - interrupts: SoC NMI / GPIO interrupt connected to the IRQ_AUDIO pin
+  - rtc
+    - compatible: "x-powers,ac100-rtc"
+    - interrupt-parent: The parent interrupt controller
+    - interrupts: SoC NMI / GPIO interrupt connected to the IRQ_RTC pin
+    - #clock-cells: shall be 1
+    - clock-output-names: "cko1_rtc", "cko2_rtc", "cko3_rtc"
+    - see clock/clock-bindings.txt for common clock bindings
+
+Example:
+
+ac100: codec@e89 {
+	compatible = "x-powers,ac100";
+	reg = <0xe89>;
+
+	ac100_codec {
+		compatible = "x-powers,ac100-codec";
+		interrupt-parent = <&nmi_intc>;
+		interrupts = <0 IRQ_TYPE_LEVEL_LOW>;
+	};
+
+	ac100_rtc {
+		compatible = "x-powers,ac100-rtc";
+		interrupt-parent = <&nmi_intc>;
+		interrupts = <0 IRQ_TYPE_LEVEL_LOW>;
+		#clock-cells = <1>;
+		clock-output-names = "cko1_rtc", "cko2_rtc", "cko3_rtc";
+	};
+};
