Subject: [PATCH v5 1/3] dt-bindings: mfd: aspeed,ast2x00-scu: Support AST2700 SoC1 pinctrl

From: Billy Tsai <[email-masked]>
Date: Thu, 21 May 2026 17:17:44 +0800

The AST2700 SoC integrates two interconnected SoC instances, each
managed by its own System Control Unit (SCU).

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.
