    "content": "This is the first step in deprecating omap_hsmmc driver completely\nand moving to sdhci-omap driver which uses the sdhci library.\n\nThis patch that adds a new SDHCI quirk \"MMC_RSP_136\" has already been\nmerged and hence removed it in this revision.\n\nApart from the quirk, sdhci-omap has it's own callbacks\nto set_clock (clock divider programming is different from generic sdhci)\n, set_power, set_bus_width, set_bus_mode and platform_send_init_74_clocks.\nThese callback functions are implemented based on omap_hsmmc driver.\nSince sdhci-omap driver requires pbias regulator fixes to be present, I've\nsent them as part of this series.\n\nThe sdhci-omap driver supports only the high speed mode and UHS/HS200\nmode will be added in a later series.\n\nIt has been tested only in boards having DRA7 SoCs like dra7-evm, dra72-evm,\nam571x-idk, am572x-idk, am57xx-evm. (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\nThe first 3 patches have also been verified not to cause any regression.\n\nNext Steps:\n*) Add UHS support to sdhci-omap\n*) Add SDIO support\n*) Add support for older TI platforms\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 ulf_next (in case someone\nwants to test)\n\nKishon Vijay Abraham I (4):\n  mmc: host: omap_hsmmc: Remove setting PBIAS voltage\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\nRavikumar Kattekola (2):\n  regulator: pbias: Select voltage table based on max-voltage\n  ARM: dts: dra7: Increase max-voltage of pbias regulator\n\n .../devicetree/bindings/mmc/sdhci-omap.txt         |  16 +\n MAINTAINERS                                        |   6 +\n arch/arm/boot/dts/dra7.dtsi                        |   2 +-\n drivers/mmc/host/Kconfig                           |  12 +\n drivers/mmc/host/Makefile                          |   1 +\n drivers/mmc/host/omap_hsmmc.c                      |  33 +-\n drivers/mmc/host/sdhci-omap.c                      | 604 +++++++++++++++++++++\n drivers/regulator/pbias-regulator.c                |  21 +-\n 8 files changed, 666 insertions(+), 29 deletions(-)\n create mode 100644 Documentation/devicetree/bindings/mmc/sdhci-omap.txt\n create mode 100644 drivers/mmc/host/sdhci-omap.c"
