2010-08-17S5P: Use accessor functions instead of SoC specific defines to access the ↵Minkyu Kang
base address This patch is intended to prepare the other S5P SoC. (s5pc210) If use SoC specific defines then can't share with other SoC. So, make the accessor functions for access the base address by common way. Signed-off-by: Minkyu Kang <mk7.kang@samsung.com> Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com>
2010-08-12mmc: omap3: fix block read functionGrazvydas Ignotas
The OMAP3 block read function is not following API and always returning 1 instead of read block count, fix it. Also to simplify code, merge it with with a helper function, which was only called from the block read function. After this patch ext2 filesystem can be used properly.

2010-06-13PXA: PXAMMC: Add Monahans supportMarek Vasut
This patch enables PXAMCI support on PXA3xx CPUs. This patch only enables MMC1 though, MMC2 and PXA31x MMC3 will need further patch to be operational. Signed-off-by: Marek Vasut <marek.vasut@gmail.com>
2010-06-13PXA: PXAMMC: Drop different delays for PXA27XMarek Vasut
In case the delays were set to 10000, the MMC card on PXA27X boards (and PXA3xx boards) didn't initialize on first try. Increasing the delays and leaving just those for PXA25x and 26x (that is 200000) fixes this problem. Signed-off-by: Marek Vasut <marek.vasut@gmail.com>

2010-04-07fsl_esdhc: Add function to reset the eSDHC controllerJerry Huang
To support multiple block read command we must set abort or use auto CMD12. If we booted from eSDHC controller neither of these are used and thus we need to reset the controller to allow multiple block read to function.

2010-03-21mxcmmc: fix warnings due to access 32 bit registers with 16 bit accessorsStefano Babic
Some registers of the mxcmmc driver were accessed using 16 bit accessor functions, because only the LSB is significant. This is not needed and generates warnings. Signed-off-by: Stefano Babic <sbabic@denx.de>
2010-03-11Fix memory leak in mmc_read()Wolfgang Denk
There is be a path through mmc_read in drivers/mmc/mmc.c where malloc'd memory is not freed before exiting mmc_read: it occurs if mmc_set_blocklen() returns a non-zero value. Reported-by: Quentin Armitage <Quentin@Armitage.org.uk> Signed-off-by: Wolfgang Denk <wd@denx.de>
2010-03-07fsl_esdhc: add support for mx51 processorStefano Babic
The esdhc controller in the mx51 processor is quite the same as the one in some powerpc processors (MPC83xx, MPC85xx). This patches adapts the driver to support the arm mx51. Signed-off-by: Stefano Babic <sbabic@denx.de>
2010-03-07MMC: add weak function to detect MMC/SD cardStefano Babic
Most controllers can check if there is a card in the slot. However, they require pins that could be not available because required by other functions and the detection of a card must be performed in another way. This patch adds a weak function that a board can implement to add its internal custom way to check the presence of a MMC/SD card. Signed-off-by: Stefano Babic <sbabic@denx.de>
2010-03-07mmc: check correctness of the voltage mask in ocrStefano Babic
Most cards do not answer if some reserved bits in the ocr are set. However, some controllers can set bit 7 (reserved for low voltages), but how to manage low voltages SD card is not yet specified. Signed-off-by: Stefano Babic <sbabic@denx.de>

2009-08-09mxc-mmc: sdhc host driver for MX2 and MX3 proccessorIlya Yanok
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. Signed-off-by: Ilya Yanok <yanok@emcraft.com>
2009-07-29OMAP3 Move twl4030 mmc functionTom Rix
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>
2009-07-19mmc: set bus width to 1 and clock to minimum early during initializationIlya Yanok
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 <yanok@emcraft.com>
2009-07-16fsl_esdhc: Add device tree fixupsAnton Vorontsov

2009-06-02mmc: Remove return from mmc_init for non SD 2.0 compatible cards.Yauhen Kharuzhy
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.

2009-06-02mmc: drop unnecessary castsRabin Vincent
Now that response is a uint, we can drop all the casts. Signed-off-by: Rabin Vincent <rabin@rab.in>
2009-06-02mmc: fix response decoding on little endianRabin Vincent
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>
2009-06-02mmc: use lldiv to fix arm eabi buildRabin Vincent
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 <rabin@rab.in>
2009-06-02mmc: check find_mmc_device return valueRabin Vincent
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 <rabin@rab.in>
