1Generic SYSCON mapped register reset driver 2 3This is a generic reset driver using syscon to map the reset register. 4The reset is generally performed with a write to the reset register 5defined by the register map pointed by syscon reference plus the offset 6with the mask defined in the reboot node. 7 8Required properties: 9- compatible: should contain "syscon-reboot" 10- regmap: this is phandle to the register map node 11- offset: offset in the register map for the reboot register (in bytes) 12- mask: the reset value written to the reboot register (32 bit access) 13 14Default will be little endian mode, 32 bit access only. 15 16Examples: 17 18 reboot { 19 compatible = "syscon-reboot"; 20 regmap = <&regmapnode>; 21 offset = <0x0>; 22 mask = <0x1>; 23 };
