This is the final part of the series originally sent as part of [2]. This series adds UHS, HS200, DDR mode and ADMA support to omap_hsmmc driver used to improve the throughput of MMC/SD in dra7 SoCs. Changes from [2]: *) No more updating omap2plus_defconfig or multi_v7_defconfig is required, so those patches are removed. *) Addressed Rob Herring's comment on implementing a function instead of having a macro while getting pinctrl state. This series is created on top of [3], [4], [5] AND [6] (i.e after ARM: dts: omap3-overo: Remove "vqmmc-supply" property from MMC dt node omap_hsmmc: use mmc_regulator_get_supply() to get regulators omap*: Fixes/Cleanups for MMC devicetree node ARM: dts: Add iodelay data for MMC) The functionality implemented in this series was sent before ([1]) but was never followed up since supporting high speed modes in dra7 required IODelay values to be configured. With IODelay driver being merged into kernel, sending it as a fresh series with support for configuring IODelay values. Suggestions of migrating to sdhci driver (from omap_hsmmc driver) is not addressed since *) tuning ratio of MMC in dra7 is different from sdhci *) IOdelay is required for dra7 *) GPIO based card detect is not supported in sdhci *) Some of the registers don't always have correct values as in sdhci (like PSTATE). Supporting all of these in sdhci will result in adding lot of quirks in sdhci driver. This series has been tested on beagleboard, pandaboard, beaglebone-black, beaglebone, am335x-evm, am437x-evm, dra7xx-evm, dra72x-evm, am571x-idk and am572x-idk. I can split the series to go into Ulf Hansson's tree and Tony's tree separately if that is required.
