[PATCH v2 3/3] arm64: dts: aspeed: Add syscon phandle to AST2700 ADC nodes

From: Billy Tsai

Date: Thu Oct 01 2026 - 06:16:31 EST


Point the ADC nodes at their own syscon1 so the driver can correctly
locate the reference-voltage trimming data on AST2700, where syscon0
and syscon1 share the same device-tree node name and would otherwise
resolve to the wrong SCU.
