From 6af057a8a5f60512ea49af028e5cf4042cb70de3 Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai Date: Tue, 10 Dec 2024 15:32:10 +0800 Subject: [PATCH] dt-bindings: mmc: mtk-sd: Document compatibles that need two register ranges Besides the MT8183's MMC controller and all its compatible derivatives, the recently added MT7986 and MT8196 also require two register ranges. This is based on the actual device trees. Properly enforce this in the binding.
