From c0238bbba7c5a45afbfe61a31c3ba322f744feb0 Mon Sep 17 00:00:00 2001 From: "Rob Herring (Arm)" Date: Mon, 15 Dec 2025 15:26:21 -0600 Subject: [PATCH] dt-bindings: mfd: Add Realtek RTD1xxx system controllers The Realtek system controllers are already in use with only generic '"syscon", "simple-mfd"' compatibles and are missing specific compatibles as required. Add a schema with specific compatibles. The labels used in .dts files serve as the basis for the names. It's doubtful the child nodes upstream are complete and I don't have documentation, so the specific child nodes aren't documented here. Of the ones in use, bindings already exist for them.
