From 338f40b3b4ff925985d3a2055ef09200778d1cd6 Mon Sep 17 00:00:00 2001 From: Shiji Yang Date: Wed, 10 Jul 2024 00:16:36 +0800 Subject: [PATCH] ramips: make SoC dtsi compatible with upstream mmc-mtk driver Add all essential MTK SDHC properties to support the new mmc-mtk driver. Since this driver relies on power regulators, we also need to enable this feature for MT7620, just like MT762{1,8}.
