*) Added comment in sdhci for disabling HS200/HS400 mode
*) Fixed a couple of chunks in "Program a relatively accurate SW timeout
value" which were missed in the previous revision

Cover letter [PATCH v5 00/14] mmc: sdhci-omap: Add UHS/HS200 mode support
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/spruhz6j/spruhz6j.pdf
(Similar to all AM57x/DRA7x SoCs). The patch series also implements workaround for errata published in
http://www.ti.com/lit/er/sprz429l/sprz429l.pdf
patches are created on top ofgit://git.kernel.org/pub/scm/linux/kernel/git/ulfh/mmc.git next
The patches along with dt has also been pushed to
https://github.com/kishon/linux-wip.git sdhci_uhs_v5
Changes from v4:
*) Added comment in sdhci for disabling HS200/HS400 mode
*) Fixed a couple of chunks in "Program a relatively accurate SW timeout
value" which were missed in the previous revision
*) Added a patch in sdhci-omap to get IODelay values of 3.3v DDR mode. *) Added pinctrl binding documentation for sdhci-omap which was missed
before.
Changes from v3:
*) Fixed Adrian's comment on error handling when __sdhci_add_host()
fails
*) Used Adrian's patches for programming SW timeout value.
Changes from v2:
*) Patches in v2 already applied to mmc -next are dropped from the
series.
*) Changed SW timeout logic as per Adrians's suggestion *) Validated SDIO with the current patches (added a couple of fixes
found while adding SDIO support).
*) Used soc_device_match() instead of pdata-quirks as per Tony's
suggestions.
Changes from v1:
*) Only poll on DAT0 and DATI for card_busy status
*) Cleanup iodelay patch as suggested by Tony.
*) Added quirk to disable HW timeout
*) Use the existing data timer but program a relatively accurate
SW timeout value (Impacts all platforms)
*) Fix a bug in sdhci which was using data_timer for non data line
commands
