+title: System Controller Registers R/W Common Properties
+
+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.
