From 30b5d9aa9aee9853b6b51d93ddf16d762d20c538 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Fri, 20 Apr 2018 18:14:24 +0900 Subject: [PATCH] mmc: tmio: move clk_enable() to each driver's probe function I need to differentiate the clock handling for uniphier-sd. Move it to each driver's probe function from the tmio common code so that renesas-sdhi will not be affected.
