(Tested only eMMC and SD.\nSDIO support will be added later). The plan is to fully convert DRA7\nSoC to use SDHCI driver and then convert other legacy platforms to use\nSDHCI.\n\nFor sdhci-omap to be functional, the following tag should be merged (There\nare no compilation dependencies).\ngit://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator\ntags/regulator-pbias-variants\n\nHowever the above regulator tag will impact omap_hsmmc driver. so [1]\nshould be merged before everything else is merged.\n\n[1] -> https://lkml.org/lkml/2017/8/31/300\n\nThe patch to add config and dts changes to use sdhci-omap will be sent\nseparately.\n\nNext Steps:\n*) Add UHS support to sdhci-omap\n*) Add SDIO support\n*) Add support for older TI platforms\n\nChanges from v3:\n*) removed omap_hsmmc and pbias-regulator patches from the series\n*) Fixed dt-binding documentation (remove '0x' in node name)\n*) stop clock if MMC core sends '0' in frequency\n\nChanges from v2:\n*) Rebased on git://git.kernel.org/pub/scm/linux/kernel/git/ulfh/mmc.git next\n*) Included a couple of patches from Ravikumar to fix pbias-regulator driver\n to support max-voltage of 3.3V. This is required for sdhci-omap driver.\n*) Create sdhci-omap as a new driver with MMC generic bindings and hence doesn't\n have bindings like ti,dual-volt added for omap-hsmmc. (Instead of\n ti,dual-volt, sdhci-omap driver uses the supported regulator voltage to\n set controller IO voltage capabilities).\n When omap-hsmmc driver is deprecated, support for these properties will\n be added to sdhci-omap.\n*) Fixed minor comments from Adrian).\n\nChanges from v1:\n*) Remove the quirks and instead use sdhci_omap specific callbacks for\n set_power, set_busmode etc.\n*) Add a patch from Adrian to tidy reading 136-bit responses\n\nI've also pushed the entire series along with dependent dt patches @\nhttps://github.com/kishon/linux-wip.git sdhci_v3 (in case someone\nwants to test)\n\nKishon Vijay Abraham I (3):\n dt-bindings: sdhci-omap: Add bindings for the sdhci-omap controller\n mmc: sdhci-omap: Add OMAP SDHCI driver\n MAINTAINERS: Add TI OMAP SDHCI Maintainer\n\n .../devicetree/bindings/mmc/sdhci-omap.txt | 16 +\n MAINTAINERS | 6 +\n drivers/mmc/host/Kconfig | 12 +\n drivers/mmc/host/Makefile | 1 +\n drivers/mmc/host/sdhci-omap.c | 607 +++++++++++++++++++++\n 5 files changed, 642 insertions(+)\n create mode 100644 Documentation/devicetree/bindings/mmc/sdhci-omap.txt\n create mode 100644 drivers/mmc/host/sdhci-omap.c" }
