From 253e0a7c3dc4bbbc69fc6bfd7c01bc4c9397a5e5 Mon Sep 17 00:00:00 2001 From: Jeongbae Seo Date: Fri, 8 Oct 2010 17:46:21 +0900 Subject: [PATCH] mmc: sdhci-s3c: Support controllers with no internal clock divider This patch supports controllers with no internal clock divider in SDHCI, such as the s5pc210 board. The external clock divider can be used to make a proper clock because SDHCI doesn't support internal clock divider by itself. If external clock divider type is selected, some functions related to clock control will be overrided by other functions. The current clock control index is added to let you know which clock bus is used for SDHCI when overriding functions. Checking functions are added into sdhci_s3c_consider_clock, because the clock divider step is different from that of host controller.
