*	mmc: mxs-mmc: fix clock rate setting	Koen Beel	2011-07-21
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Fix clock rate setting in the mxs-mmc driver. Previously, if div2 was 0 then the value for TIMING_CLOCK_RATE would have been 255 instead of 0. The limits for div1 (TIMING_CLOCK_DIVIDE) and div2 (TIMING_CLOCK_RATE+1) were also not correctly defined. Can easily be reproduced on mx23evk: default clock for high speed sdio cards is 50 MHz. With a SSP_CLK of 28.8 MHz default), this resulted in an actual clock rate of about 56 kHz. Tested on mx23evk.

*	mmc: mxs-mmc: add mmc host driver for i.MX23/28	Shawn Guo	2011-03-15
	This adds the mmc host driver for Freescale MXS-based SoC i.MX23/28. The driver calls into mxs-dma via generic dmaengine api for both pio and data transfer. Thanks Chris Ball for the indentation patch.
