title: TI J721e System Controller Registers R/W
|
|
|
|
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.
