+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";
+ };
+};
