+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
+    - #clock-cells:		Shall be 0
+    - clock-output-names:	"4M_adda"
+
+    - see clock/clock-bindings.txt for common clock bindings
+
+  - rtc
+    - compatible:		"x-powers,ac100-rtc"
+    - interrupt-parent:		The parent interrupt controller
+    - interrupts:		SoC NMI / GPIO interrupt connected to the
+    				IRQ_RTC pin
+    - clocks:			A phandle to the codec's "4M_adda" clock
+    - #clock-cells:		Shall be 1
+    - clock-output-names:	"cko1_rtc", "cko2_rtc", "cko3_rtc"
+
+    - see clock/clock-bindings.txt for common clock bindings
