[PATCH 1/6] dt-bindings: pinctrl: aspeed: Document AST2600 pinmux

[Andrew Jeffery <andrew@xxxxxxxx>]

The AST260 differs from the 2400 and 2500 in that it supports multiple
groups for a subset of functions.

+description: |+
+  The pin controller node should be the child of a syscon node with the
+  required property:
+
+  - compatible: Should be one of the following:

+
+  Refer to the the bindings described in
+  Documentation/devicetree/bindings/mfd/syscon.txt
