[PATCH v4 1/3] dt-bindings: arm: sprd: add global registers bindings

[Chunyan Zhang]

From: Chunyan Zhang <chunyan.zhang@xxxxxxxxxx>

The global registers would be used by different peripheral devices which
we can see them as syscon clients which can use regmap interface that
syscon driver provides.
