The registers are not cohesive enough to12 represent as any specific type of device. The typical use-case is13 for some other node's driver, or platform-specific code, to acquire14 a reference to the syscon node (e.g. by phandle, node path, or15 search using a specific compatible value), interrogate the node (or16 associated OS driver) to determine the location of the registers,17 and access the registers directly.18 19maintainers:20 -
