This series applies on top of "[PATCH v2 00/26] mmc: Add support for HS200
and UHS modes"

It fixes a bug with old SD and MMC cards that support only the legacy mode.
It also addresses the comments made on the mailing list:
* dump card and host capabilities in debug mode
* use 1-bit if the DTS property 'bus-width' is not present.
* recognize the "mmc-ddr-1_2v" and "mmc-hs200-1_2v" DTS properties

Tested on DRA7, DRA72 and AM335x

Jean-Jacques Hiblot (5):
  dm: mmc: updated mmc_of_parse() to not fail because of an invalid
    bus-width
  mmc: dm: support "mmc-ddr-1_2v" and "mmc-hs200-1_2v" boolean
    properties
  mmc: dump card and host capabilities if debug is enabled
  mmc: Fixed a problem with old sd or mmc that do not support High speed
  mmc: all hosts support 1-bit bus width and legacy timings
