[PATCH v4 00/12] mmc: sdhci-omap: Add UHS/HS200 mode support

From: Kishon Vijay Abraham I
Date: Wed Apr 25 2018 - 08:10:03 EST

Add UHS/HS200 mode support in sdhci-omap. The programming sequence
for voltage switching, tuning is followed from AM572x TRM
(Similar to all AM57x/DRA7x SoCs). The patch series also implements
workaround for errata published in

patches are created on top of
git://git.kernel.org/pub/scm/linux/kernel/git/ulfh/mmc.git next

Changes from v3:
*) Fixed Adrian's comment on error handling when __sdhci_add_host()
*) Used Adrian's patches for programming SW timeout value.

Changes from v2:
*) Patches in v2 already applied to mmc -next are dropped from the
*) 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

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
