1Generic SYSCON mapped register poweroff driver
2
3This is a generic poweroff driver using syscon to map the poweroff register.
4The poweroff is generally performed with a write to the poweroff register
5defined by the register map pointed by syscon reference plus the offset
6with the value and mask defined in the poweroff node.

8Required properties:
9- compatible: should contain "syscon-poweroff"
10- regmap: this is phandle to the register map node
11- offset: offset in the register map for the poweroff register (in bytes)
12- value: the poweroff value written to the poweroff register (32 bit access)
13
14Optional properties:
15- mask: update only the register bits defined by the mask (32 bit)
16
17Legacy usage:
18If a node doesn't contain a value property but contains a mask property, the
19mask property is used as the value.
20
21Default will be little endian mode, 32 bit access only.

23Examples:
24
25	poweroff {
26	   compatible = "syscon-poweroff";
27	   regmap = <&regmapnode>;
28	   offset = <0x0>;
29	   mask = <0x7a>;
30	};
