Merge tag 'mmc-v4.6' of git://git.linaro.org/people/ulf.hansson/mmc
Pull MMC updates from Ulf Hansson: "MMC core: - Fix ABI regression of MMC BLK ioctl - Remove the unused MMC_DATA_STREAM flag - Enable asynchronous system PM for the host device - Minor fixes and clean-ups SDHCI host: Throughout the years, the numbers of SDHCI variants have increased and so has also the numbers of SDHCI callbacks/quirks. The purpose of these callbacks/quirks were to enable SDHCI to deal with variant specific requirements, but unfortunate this method didn't scale. Instead we have ended up with a mess. Not only did the code become suboptimal but also highly fragile. Lately many discussions of how to move forward with SDHCI has taken place at the MMC mailing list. Step by step, we aim to turn SDHCI's common code into a set of library functions. This will enable for optimizations and allow some of the existing callbacks and quirks to be removed, which also should help to make the code less fragile. Therefore I am also really pleased to announce that Adrian Hunter (Intel) has volunteered to step in as the maintainer for SDHCI. Future wise, I hope the community around SDHCI will continue to grow and that this release cycle can be the starting point of moving SDHCI into a better shape. As a matter of fact, already in this cycle the re-factoring has begun, but of course there are also fixes and new features included. Some highlights: - sdhci-iproc: Add support for Broadcom's BCM2835 eMMC IP - sdhci-acpi: Add support for QCOM controllers - sdhci-pic32: Add new SDHCI variant for PIC32MZDA Other hosts: - atmel-mci: Fix a NULL pointer dereference - mediatek: Add SD write-protect support - mmc_spi: Fix card detect in GPIO case - tmio/sdhi: Add r8a7795 support - tmio/sdhi: Some fixes and clean-ups - dw_mmc: Add HW reset support - dw_mmc: Some fixes and clean-ups - sunxi: Add support for MMC DDR52 mode" * tag 'mmc-v4.6' of git://git.linaro.org/people/ulf.hansson/mmc: (123 commits) mmc: sdhci-of-at91: fix wake-up issue when using runtime pm mmc: sdhci-pci: Do not set DMA mask in enable_dma() mmc: sdhci-acpi: Remove enable_dma() hook mmc: sdhci: Set DMA mask when adding host mmc: block: fix ABI regression of mmc_blk_ioctl mmc: atmel-mci: Check pdata for NULL before dereferencing it at DMA config mmc: core: remove redundant memset of sdio_read_cccr mmc: core: remove redundant memset of mmc_decode_cid mmc: of_mmc_spi: fix unused warning mmc: sdhci-of-arasan: add phy support for sdhci-of-arasan mmc: sdhci-of-arasan: fix missing sdhci_pltfm_free for err handling mmc: sdhci-of-arasan: remove disable clk_ahb from sdhci_arasan_resume Documentation: bindings: add description of phy for sdhci-of-arasan mmc: sdhci: Fix override of timeout clk wrt max_busy_timeout mmc: mmci: Remove unnecessary header file mmc: sdhci-acpi: add QCOM controllers mmc: tegra: implement memcomp pad calibration mmc: mediatek: Use mmc_regulator_set_vqmmc in start_signal_voltage_switch mmc: mediatek: Change signal voltage error to dev_dbg() mmc: sh_mmcif, tmio: Use ARCH_RENESAS ...
