Subject[PATCH 00/12] mmc: sdhci-omap: Add UHS/HS200 mode support
Date
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.
