Merge tag 'mmc-updates-for-3.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/cjb/mmc
Pull MMC updates from Chris Ball: "MMC highlights for 3.8: Core: - Expose access to the eMMC RPMB ("Replay Protected Memory Block") area by extending the existing mmc_block ioctl. - Add SDIO powered-suspend DT properties to the core MMC DT binding. - Add no-1-8-v DT flag for boards where the SD controller reports that it supports 1.8V but the board itself has no way to switch to 1.8V. - More work on switching to 1.8V UHS support using a vqmmc regulator. - Fix up a case where the slot-gpio helper may fail to reset the host controller properly if a card was removed during a transfer. - Fix several cases where a broken device could cause an infinite loop while we wait for a register to update. Drivers: - at91-mci: Remove obsolete driver, atmel-mci handles these devices now. - sdhci-dove: Allow using GPIOs for card-detect notifications. - sdhci-esdhc: Fix for recovering from ADMA errors on broken silicon. - sdhci-s3c: Add pinctrl support. - wmt-sdmmc: New driver for WonderMedia SD/MMC controllers." * tag 'mmc-updates-for-3.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/cjb/mmc: (65 commits) mmc: sdhci: implement the .card_event() method mmc: extend the slot-gpio card-detection to use host's .card_event() method mmc: add a card-event host operation mmc: sdhci-s3c: Fix compilation warning mmc: sdhci-pci: Enable SDHCI_CAN_DO_HISPD for Ricoh SDHCI controller mmc: sdhci-dove: allow GPIOs to be used for card detection on Dove mmc: sdhci-dove: use two-stage initialization for sdhci-pltfm mmc: sdhci-dove: use devm_clk_get() mmc: eSDHC: Recover from ADMA errors mmc: dw_mmc: remove duplicated buswidth code mmc: dw_mmc: relocate where dw_mci_setup_bus() is called from mmc: Limit MMC speed to 52MHz if not HS200 mmc: dw_mmc: use devres functions in dw_mmc mmc: sh_mmcif: remove unneeded clock connection ID mmc: sh_mobile_sdhi: remove unneeded clock connection ID mmc: sh_mobile_sdhi: fix clock frequency printing mmc: Remove redundant null check before kfree in bus.c mmc: Remove redundant null check before kfree in sdio_bus.c mmc: sdhci-imx-esdhc: use more devm_* functions mmc: dt: add no-1-8-v device tree flag ...
