| title: System Controller Devices |
| |
| description: | |
| System controller node represents a register region containing a set |
| of miscellaneous registers. The registers are not cohesive enough to |
| represent as any specific type of device. The typical use-case is |
| for some other node's driver, or platform-specific code, to acquire |
| a reference to the syscon node (e.g. by phandle, node path, or |
| search using a specific compatible value), interrogate the node (or |
| associated OS driver) to determine the location of the registers, |
| and access the registers directly. |
