7 title: System Controller Devices

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.
