mmc: sd: Fix sd current limit setting

2012-07-22T19:25:52+00:00

Host has different current capabilities at different voltages, we need to record these settings seperately. The defined voltages are 1.8/3.0/3.3. For other voltages, we do not touch current limit setting. Before we set the current limit for the sd card, find out the host's operating voltage first and then find out the current capabilities of the host at that voltage to set the current limit.

mmc: add two capability flags for CD and WP signal polarity

To handle CD and WP SD/MMC slot pins we need generic flags to specify their polarity. Signed-off-by: Guennadi Liakhovetski Signed-off-by: Chris Ball

mmc: core: use a more generic name for slot function types and fields

struct mmc_host::hotplug is becoming a generic hook for slot functions. Rename it accordingly. Signed-off-by: Guennadi Liakhovetski Signed-off-by: Chris Ball

mmc: add a function to get regulators, supplying card's power

2012-07-21T04:02:08+00:00

Add a function to get regulators, supplying card's Vdd and Vccq on a specific host. If a Vdd supplying regulator is found, the function checks, whether a valid OCR mask can be obtained from it. The Vccq regulator is optional. A failure to get it is not fatal. Signed-off-by: Guennadi Liakhovetski Reviwed-by: Mark Brown Acked-by: Ulf Hansson Signed-off-by: Chris Ball

mmc: sdio: avoid spurious calls to interrupt handlers

2012-04-22T15:17:28+00:00

Commit 06e8935feb ("optimized SDIO IRQ handling for single irq") introduced some spurious calls to SDIO function interrupt handlers, such as when the SDIO IRQ thread is started, or the safety check performed upon a system resume. Let's add a flag to perform the optimization only when a real interrupt is signaled by the host driver and we know there is no point confirming it.

Pull MMC updates from Chris Ball: Core: * Support for MMC 4.5 Data Tag feature -- we tag REQ_META, so devices that support Data Tag will provide increased throughput for metadata. * Faster detection of card removal on I/O errors. Drivers: * dw_mmc now supports eMMC Power Off Notify, has PCI support, and implements pre_req and post_req for asynchronous requests. * omap_hsmmc now supports device tree. * esdhc now has power management support. * sdhci-tegra now supports Tegra30 devices. * sdhci-spear now supports hibernation. * tmio_mmc now supports using a GPIO for card detection. * Intel PCH now supports 8-bit bus transfers. * tag 'mmc-merge-for-3.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/cjb/mmc: (53 commits) mmc: sh_mmcif: simplify bitmask macros mmc: sh_mobile_sdhi: support modular mmc-core with non-standard hotplug mmc: sh_mobile_sdhi: add a callback for board specific init code mmc: tmio: cosmetic: prettify the tmio_mmc_set_ios() function mmc: sh_mobile_sdhi: do not manage PM clocks manually mmc: tmio_mmc: remove unused sdio_irq_enabled flag mmc: tmio_mmc: power status flag doesn't have to be exposed in platform data mmc: sh_mobile_sdhi: pass card hotplug GPIO number to TMIO MMC mmc: tmio_mmc: support the generic MMC GPIO card hotplug helper mmc: tmio: calculate the native hotplug condition only once mmc: simplify mmc_cd_gpio_request() by removing two parameters mmc: sdhci-pci: allow 8-bit bus width for Intel PCH mmc: sdhci: check interrupt flags in ISR again mmc: sdhci-pci: Add MSI support mmc: core: warn when card doesn't support HPI mmc: davinci: Poll status for small size transfers mmc: davinci: Eliminate spurious interrupts mmc: omap_hsmmc: Avoid a regulator voltage change with dt mmc: omap_hsmmc: Convert hsmmc driver to use device tree mmc: sdhci-pci: add SDHCI_QUIRK2_HOST_OFF_CARD_ON for Medfield SDIO ...

mmc: core: Detect card removal on I/O error

2012-03-27T16:19:58+00:00

To prevent I/O as soon as possible at card removal, a new detect work is re-scheduled without a delay to let a rescan remove the card device as soon as possible. Additionally, MMC_CAP2_DETECT_ON_ERR can now be used to handle "slowly" removed cards that a scheduled detect work did not detect as removed. To prevent further I/O requests for these lingering removed cards, check if card has been removed and then schedule a detect work to properly remove it.
