From 2e7410d76ad11856d09284c18d262d0bb2a3da0c Mon Sep 17 00:00:00 2001 From: Kishon Vijay Abraham I Date: Thu, 21 Sep 2017 16:30:04 +0200 Subject: [PATCH] mmc: disable the mmc clock during power off There is no point in having the mmc clock enabled during power off. Disable the mmc clock. This is similar to how it's programmed in Linux Kernel.
