From cc6adf89f9a057653fc03f4c0ba001b7db0261e9 Mon Sep 17 00:00:00 2001 From: Patrice Chotard Date: Thu, 1 Mar 2018 11:53:00 +0100 Subject: [PATCH] ARM: dts: stm32: Enable sdio1 for stm32f769-disco Adds SDIO related DT nodes for stm32f769-disco board. broken-cd property is needed as it misses a pullup on board (resistor R76 is missing).
