From 45fa59b407163abbb553d7cd333b1302e878683a Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Tue, 31 Mar 2020 19:51:25 +0200 Subject: [PATCH] ARM: dts: stm32: Repair SDMMC1 operation on AV96 The SD uses different pinmux for the D123DIRline, use such a pinmux, otherwise there is a pinmux collision on the AV96. Add missing SD voltage regulator switch and enable SDR104 operation.
