mxc-mmc: sdhc host driver for MX2 and MX3 proccessor 2009-08-09T21:47:38+00:00 Ilya Yanok yanok@emcraft.com 2009-06-08T00:12:49+00:00 ba3dbaf281130029ecb970a922551902c1d80b50 This is a port of Linux driver for SDHC host controller hardware found on Freescale's MX2 and MX3 processors. Uses new generic MMC framework (CONFIG_GENERIC_MMC) and it looks like there are some problems with a framework (at least on LE cpus). Some of these problems are addressed in the following patches.

OMAP3 Move twl4030 mmc function 2009-07-29T07:57:43+00:00 Tom Rix Tom.Rix@windriver.com 2009-06-28T17:52:31+00:00 fccc0fcaaae5154612f8259365d26d04f204859f Because twl4030 now has its own device files, move and rename twl4030_mmc_config. twl4030_mmc_config initializes the twl4030 power setting to the mmc device. Because it is in the twl4030 power domain, move it out of drivers/mmc/omap3_mmc.c and into drivers/power/twl4030.c. The function was renamed to twl4030_power_mmc_init because all the functions in this file are to have the format twl4030_power_<device>_<action> In this case the suffix is mmc_init so device : mmc action : init Signed-off-by: Tom Rix <Tom.Rix@windriver.com> Acked-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com> Acked-by: Heiko Schocher <hs@denx.de> 
Because twl4030 now has its own device files, move and rename
twl4030_mmc_config.

twl4030_mmc_config initializes the twl4030 power setting to
the mmc device.  Because it is in the twl4030 power domain, move
it out of drivers/mmc/omap3_mmc.c and into drivers/power/twl4030.c.

The function was renamed to twl4030_power_mmc_init because all
the functions in this file are to have the format

twl4030_power_<device>_<action>

In this case the suffix is mmc_init so
device : mmc
action : init

mmc: fix response decoding on little endian 2009-06-02T22:18:57+00:00 Rabin Vincent rabin@rab.in 2009-04-05T08:00:55+00:00 0b453ffe28bb9227d86ddbe0893bd19c93f04ed7 The mmc code defines the response as an array of chars. However, it access the response bytes both as (i) an array of four uints (with casts) and (ii) as individual chars. The former case is used more often, including by the driver when it assigns the response. The char-wise accesses are broken on little endian systems because they assume that the bytes in the uints are in big endian byte order. This patch fixes this by changing the response to be an array of four uints and replacing the char-wise accesses with equivalent uint-wise accesses. Signed-off-by: Rabin Vincent <rabin@rab.in>
