| * mmc: sdhci: Intel Medfield supportXiaochen Shen2010-10-23

| * mmc: sdhci: Allow the probe handler to override slotsAlan Cox2010-10-23
| | | | | | | | | | | | | | | | | | Currently we write it to the chip data, but if the probe handler overrides it we ignore the new value and keep using our cached one. Fix this so that a probe handler can adjust the slot count. Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Chris Ball <cjb@laptop.org>
| * mmc: sdhci: split up sdhci.h for sdhci-pltfm usersGiuseppe Cavallaro2010-10-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some platforms based on sdhci-pltfm need to set their own quirks. Previously to this patch, the quirks were in drivers/mmc/host/sdhci.h. This patch splits drivers/mmc/host/sdhci.h into two parts: * drivers/mmc/host/sdhci.h includes the HC registers and I/O accessors. * include/linux/mmc/sdhci.h includes the sdhci structure and quirks. Instead of including drivers/mmc/host/sdhci.h, -pltfm drivers should now include include/linux/mmc/sdhci.h and include/linux/sdhci-pltfm.h. This patch avoids adding/changing the calls/flags in the sdhci_pltfm_data structure. It has been tested on STM platforms (e.g. STx7106, STx7108, STx5206) where the driver is configured and used as shown in the example below: [snip] static int mmc_pad_resources(struct sdhci_host *sdhci) { if (!devm_stm_pad_claim(sdhci->mmc->parent, &stx7108_mmc_pad_config, dev_name(sdhci->mmc->parent))) return -ENODEV; return 0; } static struct sdhci_pltfm_data stx7108_mmc_platform_data = { .init = mmc_pad_resources, .quirks = SDHCI_QUIRK_NO_ENDATTR_IN_NOPDESC, }; static struct platform_device stx7108_mmc_device = { .name = "sdhci", [snip] Note: drivers/mmc/host/sdhci.h now also includes linux/mmc/sdhci.h, and no modifications should be needed on other sdhci-<XXX> drivers.

| * mmc: Move regulator handling closer to coreLinus Walleij2010-10-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After discovering a problem in regulator reference counting I took Mark Brown's advice to move the reference count into the MMC core by making the regulator status a member of struct mmc_host. I took this opportunity to also implement NULL versions of the regulator functions so as to rid the driver code from some ugly #ifdef CONFIG_REGULATOR clauses.

| * mmc: sdhci: disable MMC_CAP_NEEDS_POLL in nonremovable caseJaehoon Chung2010-10-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a controller requires SDHCI_QUIRK_BROKEN_CARD_DETECTION, we poll for card insertion/removal, and that creates interrupts. There's no need to be doing this if we have a non-removable card. This patch requires cards to be removable before we're willing to set MMC_CAP_NEEDS_POLL.

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.

* | | mmc: sdhci-s3c: fix incorrect spinlock usage after mergeMarek Szyprowski2010-09-26
| |/ |/| | | | | | | | | | | | | | | | | | | | | In the commit f522886e202a34a2191dd5d471b3c4d46410a9a0 a merge conflict in the sdhci-s3c driver been fixed. However the fix used incorrect spinlock operation - it caused a race with sdhci interrupt service. The correct way to solve it is to use spin_lock_irqsave/irqrestore() calls.

* | omap hsmmc: fix a racing case between kmmcd and omap_hsmmc_suspendEthan Du2010-09-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | tmio_mmc: don't clear unhandled pending interruptsYusuke Goda2010-09-09
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | 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()."
