From 9f24b0f2542f60bde7b699469a97cd852e1eed79 Mon Sep 17 00:00:00 2001 From: Stefan Wahren Date: Sun, 17 Jan 2016 14:59:01 +0000 Subject: mmc: sdhci-iproc: Actually enable the clock The RPi firmware-based clocks driver can actually disable unused clocks, so when switching to use it we ended up losing our MMC clock once all devices were probed. This patch adopts the changes from 1e5a0a9a58e2 ("mmc: sdhci-bcm2835: Actually enable the clock") to sdhci-iproc.
