From 27fbce4326a4d2134791784e054c7acb62ee6761 Mon Sep 17 00:00:00 2001 From: Yann Gautier Date: Tue, 13 Sep 2022 13:23:45 +0200 Subject: [PATCH] mmc: stm32_sdmmc2: protect against unsupported modes The UHS modes for SD, HS200 and HS400 modes for eMMC are not supported by the stm32_sdmmc2 driver. Make it clear by removing the corresponding caps after parsing the DT.
