Add UHS/HS200 mode support in sdhci-omap. The programming sequence for voltage switching, tuning is followed from AM572x TRM http://www.ti.com/lit/ug/spruhz6i/spruhz6i.pdf (Similar to all AM57x/DRA7x SoCs). The patch series also implements workaround for errata published in http://www.ti.com/lit/er/sprz429k/sprz429k.pdf. While most of this series is specific to sdhci-omap, it also patches sdhci to use software timer when the requested timeout is greater than hardware capablility. This re-uses the SW data timer already implemented in sdhci while disabling the HW timeout (so that spurious timeout is not observed). The patch for sdhci.c is based on an earlier patch that was done specific to omap_hsmmc.c (https://patchwork.kernel.org/patch/9791449/) It also includes a pdata-quirk patch since both pdata-quirks and sdhci-omap uses struct sdhci_omap_platform_data. The dt patches enabling UHS/HS200 will be follow this patch series.
