Merge tag 'mmc-merge-for-3.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/cjb/mmc
Pull MMC updates from Chris Ball: "Core: - Add DT properties for card detection (broken-cd, cd-gpios, non-removable) - Don't poll non-removable devices - Fixup/rework eMMC sleep mode/"power off notify" feature - Support eMMC background operations (BKOPS). To set the one-time programmable fuse that enables bkops on an eMMC that doesn't already have it set, you can use the "mmc bkops enable" command in: git://git.kernel.org/pub/scm/linux/kernel/git/cjb/mmc-utils.git Drivers: - atmel-mci, dw_mmc, pxa-mci, dove, s3c, spear: Add device tree support - bfin_sdh: Add support for the controller in bf60x - dw_mmc: Support Samsung Exynos SoCs - eSDHC: Add ADMA support - sdhci: Support testing a cd-gpio (from slot-gpio) instead of presence bit - sdhci-pltfm: Support broken-cd DT property - tegra: Convert to only supporting DT (mach-tegra has gone DT-only)" * tag 'mmc-merge-for-3.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/cjb/mmc: (67 commits) mmc: core: Fixup broken suspend and eMMC4.5 power off notify mmc: sdhci-spear: Add clk_{un}prepare() support mmc: sdhci-spear: add device tree bindings mmc: sdhci-s3c: Add clk_(enable/disable) in runtime suspend/resume mmc: core: Replace MMC_CAP2_BROKEN_VOLTAGE with test for fixed regulator mmc: sdhci-pxav3: Use sdhci_get_of_property for parsing DT quirks mmc: dt: Support "broken-cd" property in sdhci-pltfm mmc: sdhci-s3c: fix the wrong number of max bus clocks mmc: sh-mmcif: avoid oops on spurious interrupts mmc: sh-mmcif: properly handle MMC_WRITE_MULTIPLE_BLOCK completion IRQ mmc: sdhci-s3c: Fix crash on module insertion for second time mmc: sdhci-s3c: Enable only required bus clock mmc: Revert "mmc: dw_mmc: Add check for IDMAC configuration" mmc: mxcmmc: fix bug that may block a data transfer forever mmc: omap_hsmmc: Pass on the suspend failure to the PM core mmc: atmel-mci: AP700x PDC is not connected to MCI mmc: atmel-mci: DMA can be used with other controllers mmc: mmci: use clk_prepare_enable and clk_disable_unprepare mmc: sdhci-s3c: Add device tree support mmc: dw_mmc: add support for exynos specific implementation of dw-mshc ...
