-Generic SYSCON mapped register poweroff driver
-
-This is a generic poweroff driver using syscon to map the poweroff register.
-The poweroff is generally performed with a write to the poweroff register
-defined by the register map pointed by syscon reference plus the offset
-with the value and mask defined in the poweroff node.
-
-Required properties:
-- compatible: should contain "syscon-poweroff"
-- regmap: this is phandle to the register map node
-- offset: offset in the register map for the poweroff register (in bytes)
-- value: the poweroff value written to the poweroff register (32 bit access)
-
-Optional properties:
-- mask: update only the register bits defined by the mask (32 bit)
-
-Legacy usage:
-If a node doesn't contain a value property but contains a mask property, the
-mask property is used as the value.
-
-Default will be little endian mode, 32 bit access only.
-
-Examples:
-
-	poweroff {
-	   compatible = "syscon-poweroff";
-	   regmap = <&regmapnode>;
-	   offset = <0x0>;
-	   mask = <0x7a>;
-	};
