* System Controller Registers R/W driverSystem controller node represents a register region containing a setof miscellaneous registers. The registers are not cohesive enough torepresent as any specific type of device. The typical use-case is forsome other node's driver, or platform-specific code, to acquire areference to the syscon node (e.g. by phandle, node path, or searchusing a specific compatible value), interrogate the node (or associatedOS driver) to determine the location of the registers, and access theregisters directly.Required properties:- compatible: Should contain "syscon".- reg: the register region can be accessed from syscon
