Allow the AST2700 SoC1 pin controller to be described as a child node of the SCU by extending the compatible strings accepted by the SCU binding. There is no functional change to the SCU binding beyond permitting the aspeed,ast2700-soc1-pinctrl compatible string. Signed-off-by: Billy Tsai --- Note: This patch modifies Documentation/devicetree/bindings/mfd/aspeed,ast2x00-scu.yaml, which is also touched by the AST2700 SoC0 pinctrl series and may conflict if both series are applied independently. The conflict is trivial as both series add new compatible entries and can be resolved by keeping both.
