1X-Powers AC100 Codec/RTC IC Device Tree bindings
2
3AC100 is a audio codec and RTC subsystem combo IC. The 2 parts are
4separated, including power supplies and interrupt lines, but share
5a common register address space and host interface.

7Required properties:
8- compatible: "x-powers,ac100"
9- reg: The I2C slave address or RSB hardware address for the chip
10- sub-nodes:
11  - codec
12    - compatible:		"x-powers,ac100-codec"
13    - interrupts:		SoC NMI / GPIO interrupt connected to the
14    				IRQ_AUDIO pin
15    - #clock-cells:		Shall be 0
16    - clock-output-names:	"4M_adda"
17
18    - see clock/clock-bindings.txt for common clock bindings
19
20  - rtc
21    - compatible:		"x-powers,ac100-rtc"
22    - clocks:			A phandle to the codec's "4M_adda" clock
23    - #clock-cells:		Shall be 1
24    - clock-output-names:	"cko1_rtc", "cko2_rtc", "cko3_rtc"
