| 9 | description: | |
| 10 | System controller node represents a register region containing a set |
| 11 | of miscellaneous registers. 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. |
