From 02fe7ca03166ed8be6278dec14c2ce2be9abf668 Mon Sep 17 00:00:00 2001 From: "Rob Herring (Arm)" Date: Tue, 14 Oct 2025 10:30:38 -0500 Subject: [PATCH] dt-bindings: arm: Convert Marvell AP80x System Controller to DT schema Convert the Marvell AP80x System Controller binding to DT schema format. There's not any specific compatible for the whole block which is a separate problem, so just the child nodes are documented. Only the pinctrl and clock child nodes need to be converted as the GPIO node already has a schema.
