The registers are not cohesive enough to 12 represent as any specific type of device. The typical use-case is 13 for some other node's driver, or platform-specific code, to acquire 14 a reference to the syscon node (e.g. by phandle, node path, or 15 search using a specific compatible value), interrogate the node (or 16 associated OS driver) to determine the location of the registers, 17 and access the registers directly. 18 19maintainers: 20 -
