+title: TI J721e System Controller Registers R/W Device Tree Bindings
+
+description: |
+ This represents the Control Module registers (CTRL_MMR0) on the SoC.
+ 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.
