Merge tag 'mmc-v7.4' of git://git.kernel.org/pub/scm/linux/kernel/git/ulfh/mmc
Pull MMC updates from Ulf Hansson: "MMC core: - Add a power-off-delay-us DT property to support HW specific delays - Add mmc_send_tuning_timeout() to allow hosts to specify a timeout - Enable hosts to control the re-programming of the crypto keys MMC host: - dw_mmc: Add a common watchdog and convert the various timeouts to use it - dw_mmc: Expose the watchdog state in debugfs - dw_mmc-rockchip: Use a tighter per command tuning timeout - greybus-sdio: Convert to devm_mmc_alloc_host() - meson-gx: Enable the bus pipeline clock on T7 - rtsx_usb_sdmmc: Start card power-up at 3.3V - sdhci-cadence: Add Altera Agilex5 SD6HC support - sdhci-cadence: Add Cadence SD6HC support - sdhci-msm: Add support for the MSM8952 and Maili variants - sdhci-msm: Use pm ops to better manage restoring of crypto keys - sdhci-of-dwcmshc: Disable CQE error halt request for Rockchip - sdhci-pxav3: Disable clock inversion for SD HS cards - sunplus: Fixup initialization for DDR modes - sunxi: Add support for Allwinner B288 - vub300: Remove the driver for the obsolete HW" * tag 'mmc-v7.4' of git://git.kernel.org/pub/scm/linux/kernel/git/ulfh/mmc: (43 commits) dt-bindings: mmc: sun4i-a10-mmc: add Allwinner B288 mmc: dw_mmc-rockchip: use a tighter per-command tuning timeout mmc: core: add mmc_send_tuning_timeout() mmc: sdhci-of-dwcmshc: Disable CQE error halt request for Rockchip dt-bindings: mmc: sdhci-msm: Add MSM8952 compatible mmc: use assign_bit() where applicable mmc: sdhci-pci: Replace deprecated PCI functions mmc: sunplus: initialise rd_crc_dly=1 for DDR modes mmc: core: fix stale mmc_start_req() references in comments docs: mmc: fix stale async request documentation docs: mmc: document eMMC health status support in mmc-tools mmc: cavium-thunderx: Drop redundant calls to get|put_device() mmc: core: Turn mmc_alloc|free_host() into static functions staging: greybus: sdio: Convert to devm_mmc_alloc_host() mmc: vub300: Remove the driver for the obsolete HW mmc: dw_mmc: remove unused slot member mmc: sdhci-pxav3: avoid of_node CREDITS: Add Pierre Ossman mmc: fix typos in comments mmc: meson-gx: enable the bus pipeline clock on T7 ...
