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
* convert mmc_of_parse to livetree
Tested on DRA7, DRA72 and AM335x
changes since v2:
* use the device-oriented helpers like dev_read_u32_default() instead of using
the livetree API
* Dump the host and card capabilities only in when debug is enabled. Also dump
the capabilities when 'mmc info' is executed if the verbose option is enabled
changes since v1:
* convert mmc_of_parse to livetree
* squashed all changes to mmc_of_parse in a single patch
