Rob Herring 4828556dca dt-bindings: Use 'additionalProperties' instead of 'unevaluatedProperties'
In cases where we don't reference another schema, 'additionalProperties'
can be used instead. This is preferred for now as 'unevaluatedProperties'
support isn't implemented yet.

In a few cases, this means adding some missing property definitions of
which most are for SPI bus properties. 'unevaluatedProperties' is not going
to work for the SPI bus properties anyways as they are evaluated from the
parent node, not the SPI child node.

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.
