From 32d4878b26c1c69c893c6a1f6f7004d1bcc57a79 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Thu, 14 Jan 2021 15:52:10 +0100 Subject: [PATCH] ARM: dts: stm32: Disable SDMMC1 CKIN feedback clock on DHCOM The STM32MP1 DHCOM SoM can be built with either bus voltage level shifter or without one on the SDMMC1 interface. Because the SDMMC1 interface is limited to 50 MHz and hence SD high-speed anyway, disable the SD feedback clock to permit operation of the same U-Boot image on both SoM with and without voltage level shifter.
