Split Samsung Exynos SoC SYSREG bindings to own file to narrow the bindings and do not allow other parts of syscon.yaml. This allows further customization of Samsung SoC bindings.

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