Boojin Kim 51ddf31da1 ARM: SAMSUNG: Remove Samsung specific enum type for dma direction
This patch removes the samsung specific enum type 's3c2410_dmasrc'
and uses 'dma_data_direction' instead.

Seungwon Jeon 6daa777866 mmc: dw_mmc: Fix DDR mode support.
Host driver can't get a hint of DDR mode through ios->ddr flag anymore.
ios->timing is currently used to inform DDR mode as a substitute.
And capability of MMC_CAP_MMC_HIGHSPEED is added for DDR support.

Andy Shevchenko 65be3fef93 mmc: sdhci: use f_max instead of host->clock for timeouts
When timeout_clk is calculated the host->clock could be zero.
So, instead of host->clock the calculation now uses mmc->f_max.

Andy Shevchenko 272308caaa mmc: sdhci: move timeout_clk calculation farther down
This moves the calculation below the assignment of mmc->f_max, which
we need for calculating timeout_clk in the next patch in this series.

Andy Shevchenko 78a2ca2727 mmc: sdhci: check host->clock before using it as a denominator
Sometimes host->clock could be zero which is a legal situation. This
patch checks host->clock before usage as a denominator when timeout is
calculated. A similar patch is applied for mmc core (see commit e9b8684,
"mmc: fix division by zero in MMC core").

Without this patch, the execution of the sdhci_calc_timeout could end up
with a backtrace:
