mmc: set bus width to 1 and clock to minimum early during initialization

2009-07-19T20:07:29Z

We need to switch back to 1-bit before initialization or SD 2.0 cards will fail to send SCR if we've switched to 4-bit already. Signed-off-by: Ilya Yanok

fsl_esdhc: Add device tree fixups

2009-07-16T20:24:06Z

This patch implements fdt_fixup_esdhc() function that is used to fixup the device tree. The function adds status = "disabled" propery if esdhc pins muxed away, otherwise it fixups clock-frequency for esdhc nodes. Signed-off-by: Anton Vorontsov Acked-by: Kim Phillips

mmc: Fix decoding of SCR & function switch data on little-endian machines

2009-06-02T22:20:04Z

SCR & switch data are read from card as big-endian words and should be converted to CPU byte order. Signed-off-by: Yauhen Kharuzhy Signed-off-by: Andy Fleming

mmc: Remove return from mmc_init for non SD 2.0 compatible cards.

2009-06-02T22:19:07Z

Cards which are not compatible with SD 2.0 standard, may return response for CMD8 command, but it will be invalid in terms of SD 2.0. We should accept this case as admissible, just like Linux does. Signed-off-by: Yauhen Kharuzhy Signed-off-by: Andy Fleming

mmc: drop unnecessary casts

2009-06-02T22:18:57Z

Now that response is a uint, we can drop all the casts. Signed-off-by: Rabin Vincent

mmc: fix response decoding on little endian

2009-06-02T22:18:57Z

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

mmc: use lldiv to fix arm eabi build

2009-06-02T22:18:56Z

The generic MMC core uses direct long long divisions, which do not build with ARM EABI toolchains. Use lldiv() instead, which works everywhere. Signed-off-by: Rabin Vincent

mmc: check find_mmc_device return value

2009-06-02T22:18:56Z

find_mmc_device returns NULL if an invalid device number is specified. Check for this to avoid dereferencing NULL pointers. Signed-off-by: Rabin Vincent

Replace attribute references with attribute__

2009-04-27T23:01:39Z

__attribute__ follows gcc's documented syntax and is generally more common than __attribute. This change is only asthetic and should not affect functionality. Signed-off-by: Peter Tyser

Blackfin: convert bfin_sdh to legacy mmc

2009-04-02T10:42:05Z

The Blackfin SDH controller is still using the legacy framework, so update the driver to use the renamed functions. Signed-off-by: Mike Frysinger
