* ppc/85xx: PIO Support for FSL eSDHC Controller DriverDipen Dudhat2010-04-23-2/+85
| | | | | | | On some Freescale SoC Internal DMA of eSDHC controller has bug. So PIO Mode has been introduced to do data transfer using CPU. Signed-off-by: Dipen Dudhat <dipen.dudhat@freescale.com>
* fsl_esdhc: Only modify the field we are changing in WMLRoy Zang2010-04-07-5/+4
| | | | | | | | | When we set the read or write watermark in WML we should maintain the rest of the register as is, rather than using some hard coded value.

* fsl_esdhc: Add function to reset the eSDHC controllerJerry Huang2010-04-07-0/+17
| | | | | | | | | | | | 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.

* fsl_esdhc: Always stop clock before changing frequencyKumar Gala2010-04-07-8/+3
| | | | | | | | We need to stop the clocks on 83xx/85xx as well as imx. No need to make this code conditional to just imx. Signed-off-by: Kumar Gala <galak@kernel.crashing.org> Acked-by: Stefano Babic <sbabic@denx.de>
* mxcmmc: fix warnings due to access 32 bit registers with 16 bit accessorsStefano Babic2010-03-21-18/+18
| | | | | | | | | 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>
* Fix memory leak in mmc_read()Wolfgang Denk2010-03-11-1/+1
| | | | | | | | | 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>
* fsl_esdhc: add support for mx51 processorStefano Babic2010-03-07-48/+101
| | | | | | | | | 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>
* MMC: add weak function to detect MMC/SD cardStefano Babic2010-03-07-0/+7
| | | | | | | | | | | 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>
* mmc: check correctness of the voltage mask in ocrStefano Babic2010-03-07-1/+9
| | | | | | | | | | 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>

* omap3_mmc: Encapsulate twl4030 under option CONFIG_TWL4030_POWERVaibhav Hiremath2009-11-27-0/+2
| | | | | | | Fixes the build/compilation error if we try to re-use the omap3_mmc code without TWL4030_POWER. Signed-off-by: Vaibhav Hiremath <hvaibhav@ti.com>

* mxc-mmc: sdhc host driver for MX2 and MX3 proccessorIlya Yanok2009-08-09-0/+524
| | | | | | | | | | 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>
* OMAP3 Move twl4030 mmc functionTom Rix2009-07-29-11/+2
| | | | | | | | | | | | | | | | | | | | | | 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>
* mmc: set bus width to 1 and clock to minimum early during initializationIlya Yanok2009-07-19-0/+3
| | | | | | | 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>
* fsl_esdhc: Add device tree fixupsAnton Vorontsov2009-07-16-0/+19
| | | | | | | | | | | 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.

* mmc: Fix decoding of SCR & function switch data on little-endian machinesYauhen Kharuzhy2009-06-02-5/+5
| | | | | | | | SCR & switch data are read from card as big-endian words and should be converted to CPU byte order. Signed-off-by: Yauhen Kharuzhy <jekhor@gmail.com> Signed-off-by: Andy Fleming <afleming@freescale.com>
* mmc: Remove return from mmc_init for non SD 2.0 compatible cards.Yauhen Kharuzhy2009-06-02-4/+0
| | | | | | | | | 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 <jekhor@gmail.com> Signed-off-by: Andy Fleming <afleming@freescale.com>
* mmc: drop unnecessary castsRabin Vincent2009-06-02-15/+15
| | | | | | Now that response is a uint, we can drop all the casts. Signed-off-by: Rabin Vincent <rabin@rab.in>
* mmc: fix response decoding on little endianRabin Vincent2009-06-02-10/+10
| | | | | | | | | | | | | | | | 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>
* mmc: use lldiv to fix arm eabi buildRabin Vincent2009-06-02-3/+4
| | | | | | | 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>
* mmc: check find_mmc_device return valueRabin Vincent2009-06-02-1/+1
| | | | | | | 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>
* Replace __attribute references with __attribute__Peter Tyser2009-04-28-2/+2
| | | | | | | | __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 <ptyser@xes-inc.com>
* Blackfin: convert bfin_sdh to legacy mmcMike Frysinger2009-04-02-12/+2

* Add MMC FrameworkAndy Fleming2009-02-16-0/+931
| | | | | | | | | | | | | | Here's a new framework (based roughly off the linux one) for managing MMC controllers. It handles all of the standard SD/MMC transactions, leaving the host drivers to implement only what is necessary to deal with their specific hardware. This also hooks the infrastructure into the PowerPC board code (similar to how the ethernet infrastructure now hooks in) Some of this code was contributed by Dave Liu <daveliu@freescale.com> Signed-off-by: Andy Fleming <afleming@freescale.com>
