Merge tag 'mmc-updates-for-3.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/cjb/mmc
Pull MMC updates from Chris Ball: "MMC highlights for 3.12: Core: - Support Allocation Units 8MB-64MB in SD3.0, previous max was 4MB. - The slot-gpio helper can now handle GPIO debouncing card-detect. - Read supported voltages from DT "voltage-ranges" property. Drivers: - dw_mmc: Add support for ARC architecture, and support exynos5420. - mmc_spi: Support CD/RO GPIOs. - sh_mobile_sdhi: Add compatibility for more Renesas SoCs. - sh_mmcif: Add DT support for DMA channels" * tag 'mmc-updates-for-3.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/cjb/mmc: (50 commits) Revert "mmc: tmio-mmc: Remove .set_pwr() callback from platform data" mmc: dw_mmc: Add support for ARC mmc: sdhci-s3c: initialize host->quirks2 for using quirks2 mmc: sdhci-s3c: fix the wrong register value, when clock is disabled mmc: esdhc: add support to get voltage from device-tree mmc: sdhci: get voltage from sdhc host mmc: core: parse voltage from device-tree mmc: omap_hsmmc: use the generic config for omap2plus devices mmc: omap_hsmmc: clear status flags before starting a new command mmc: dw_mmc: exynos: Add a new compatible string for exynos5420 mmc: sh_mmcif: revision-specific CLK_CTRL2 handling mmc: sh_mmcif: revision-specific Command Completion Signal handling mmc: sh_mmcif: add support for Device Tree DMA bindings mmc: sh_mmcif: move header include from header into .c mmc: SDHI: add DT compatibility strings for further SoCs mmc: dw_mmc-pci: enable bus-mastering mode mmc: dw_mmc-pci: get resources from a proper BAR mmc: tmio-mmc: Remove .set_pwr() callback from platform data mmc: tmio-mmc: Remove .get_cd() callback from platform data mmc: sh_mobile_sdhi: Remove .set_pwr() callback from platform data ...
