8 title: TI J721e System Controller Registers R/W Device Tree Bindings
11 This represents the Control Module registers (CTRL_MMR0) on the SoC.
12 System controller node represents a register region containing a set
13 of miscellaneous registers. The registers are not cohesive enough to
14 represent as any specific type of device. The typical use-case is
15 for some other node's driver, or platform-specific code, to acquire
16 a reference to the syscon node (e.g. by phandle, node path, or
17 search using a specific compatible value), interrogate the node (or
18 associated OS driver) to determine the location of the registers,
19 and access the registers directly.
