The "6882a8c sdhci: Add better ADMA error reporting" commit added sdhci_show_adma_error() which is built when DEBUG is defined.

2010-10-01omap4 hsmmc: Update ocr mask for MMC2 for regulator to usekishore kadiyala
On OMAP4, MMC2 controller has eMMC which draws power from VAUX regulator on TWL. Though the eMMC supports dual voltage[1.8v/3v] as per ocr register, its VCC is fixed at 3V for operation. With this once the mmc core selects the minimum voltage[1.8] supported based on the ocr value read from OCR register, eMMC will not get detected. Thus the platform data for MMC2 is updated with ocr mask and same will be communicated to core which will set the regulator to always operate at 3V when ever turned ON.

In OMAP4, as per new PM programming model, the legacy registers which were there in OMAP3 are all shifted by 0x100 while new one's are added from offset 0 to 0x10. For OMAP4, the register offset appending of 0x100 done in devices.c currently, is moved to driver file.This change fits in for current implementation as well as once the driver undergoes hwmod adaptation.

2010-09-09omap hsmmc: fix a racing case between kmmcd and omap_hsmmc_suspendEthan Du
If suspend called when kmmcd is doing host->ops->disable, as kmmcd already increased host->en_dis_recurs to 1, the mmc_host_enable in suspend function will return directly without increase the nesting_cnt, which will cause the followed register access carried out to the disabled host. mmc_suspend_host will enable host itself. No need to enable host before it. Also works on kmmcd will get flushed in mmc_suspend_host, enable host after it will be safe. So make the mmc_host_enable after it.

2010-09-09tmio_mmc: don't clear unhandled pending interruptsYusuke Goda
Previously, it was possible for ack_mmc_irqs() to clear pending interrupt bits in the CTL_STATUS register, even though the interrupt handler had not been called. This was because of a race that existed when doing a read-modify-write sequence on CTL_STATUS. After the read step in this sequence, if an interrupt occurred (causing one of the bits in CTL_STATUS to be set) the write step would inadvertently clear it. Observed with the TMIO_STAT_RXRDY bit together with CMD53 on AR6002 and BCM4318 SDIO cards in polled mode. This patch eliminates this race by only writing to CTL_STATUS and clearing the interrupts that were passed as an argument to ack_mmc_irqs()."

2010-08-11sdhci: add regulator supportMarek Szyprowski
This patch adds support for regulator API to sdhci core driver. Regulators can be used to disable power in suspended state to reduce dissipated energy.

2010-08-11sdhci-s3c: add support for new card detection methodsMarek Szyprowski
On some Samsung SoCs not all SDHCI controllers have card detect (CD) line. For some embedded designs it is not even needed, because ususally the device (like SDIO flash memory or wifi controller) is permanently wired to the controller. There are also systems which have a card detect line connected to some of the external interrupt lines or the presence of the card depends on some other actions (like enabling a power regulator). This patch adds support for all these cases. The following card detection methods are possible: 1. internal sdhci host card detect line 2. external event 3. external gpio interrupt 4. no card detect line, controller will poll for the card 5. no card detect line, card is permanently wired to the controller (once detected host won't poll it any more) By default, all existing code would use method #1, what is compatible with the previous version of the driver. In case of external event, two callbacks must be provided in platdata: ext_cd_init and ext_cd_cleanup. Both of them get a callback to a function that notifies the s3c-sdhci host contoller as their argument. That callback function should be called from the even dispatcher to let host notice the card insertion/removal. In case of external gpio interrupt, a gpio pin number must be provided in platdata (ext_cd_gpio parameter), as well as the information about the polarity of that gpio pin (ext_cd_gpio_invert). By default (ext_cd_gpio_invert == 0) gpio value 0 means 'card has been removed', but this can be changed to 'card has been removed' when ext_cd_gpio_invert == 1. This patch adds all required changes to sdhci-s3c driver.

2010-08-11sdhci-s3c: enable SDHCI_QUIRK_NO_HISPD_BIT quirkMarek Szyprowski
This patch enables SDHCI_QUIRK_NO_HISPD_BIT on Samsung SDHCI driver. This solves detection problems with some external SD cards. This change has been tested on S5PC100 and S5PC110. It has no inpact on driver speed.

2010-08-11sdhci-s3c: add support for the non standard minimal clock valueMarek Szyprowski
S3C SDHCI host controller can change the source for generating mmc clock. By default host bus clock is used, what causes some problems on machines with 133MHz bus, because the SDHCI divider cannot be as high get proper clock value for identification mode. This is not a problem for the controller, because it can generate lower frequencies from other clock sources. This patch changes sdhci driver to use get_min_clock() call if it has been provided. This fixes the flood of the following warnings on Samsung S5PV210 SoCs: mmc0: Minimum clock frequency too high for identification mode Signed-off-by: Marek Szyprowski <m.szyprowski@samsung.com> Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com> Cc: <linux-mmc@vger.kernel.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2010-08-11sdhci-s3c: add SDHCI_QUIRK_DATA_TIMEOUT_USES_SDCLK quirkHyuk Lee
On Samsung's SDMMC hosts the timeout clock is derivied from the SD Clock which is set dynamically. So checked SDHCI_QUIRK_DATA_TIMEOUT_USES_SDCLK quirk and removed 'sdhci_s3c_get_timeout_clk' callback which doesn't need any more.
