From c34eda69ad4c8be618ee95627b3e9ea052cf2324 Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Fri, 25 Aug 2017 11:49:53 +0200 Subject: [PATCH] mmc: sunxi: Reset the device at probe time We might be into some troubles if the bootloader misconfigured the MMC controller. We currently only de-assert the reset line at probe time, which means that if the device was already out of reset, we're going to keep whatever state was set already. Switch to a reset instead of the deassert to have a device in a pristine state when we start operating.
