From 1d405e207bb176c937d44f9a5f87e268022c2416 Mon Sep 17 00:00:00 2001 From: Siva Durga Prasad Paladugu <siva.durga.paladugu@xilinx.com> Date: Thu, 25 Feb 2016 12:51:50 +0530 Subject: [PATCH] mmc: sdhci: Disable internal clock enable bit Disable internal clock by clearing the internal clock enable bit. This bit needs to be cleared too when we stop the SDCLK for changing the frequency divisor. This bit should be set to zero when the device is not using the Host controller.
