The X-Powers AC100 hybrid devices are supported by Linux thanks to its
device tree binding.

Now that we have the DT validation in place, let's convert the device
tree bindings for that driver over to a YAML schema.

-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"
-    - 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"
-    - 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
-
-Example:
-
-ac100: codec@e89 {
-	compatible = "x-powers,ac100";
-	reg = <0xe89>;
-
-	ac100_codec: codec {
-		compatible = "x-powers,ac100-codec";
-		interrupt-parent = <&r_pio>;
-		interrupts = <0 9 IRQ_TYPE_LEVEL_LOW>; /* PL9 */
-		#clock-cells = <0>;
-		clock-output-names = "4M_adda";
-	};
-
-	ac100_rtc: rtc {
-		compatible = "x-powers,ac100-rtc";
-		interrupt-parent = <&nmi_intc>;
-		interrupts = <0 IRQ_TYPE_LEVEL_LOW>;
-		clocks = <&ac100_codec>;
-		#clock-cells = <1>;
-		clock-output-names = "cko1_rtc", "cko2_rtc", "cko3_rtc";
-	};
-};
