From 5d0434315c46a3a038a9842a6627f6a57d1538da Mon Sep 17 00:00:00 2001 From: Przemyslaw Marczak Date: Wed, 28 Oct 2015 15:41:49 +0100 Subject: [PATCH] Exynos4412: pinmux: disable pull for MMC pins There are 8 pins for SD card in Exynos, but the MUX was configured only for 7, since the one was used for card detection. This caused the pin's pull wrong configuration. This commit fixes this and the card detect can work properly, after call this function. Tested-on: Odroid U3 and Odroid X2.
