Hi Guennadi,

This patch does not intend to add any custom mmc properties. I checked
your patch (in the link mentioned above) and most of the bindings are
similar to what you have come up with except for the "ro-gpios" for
which I have used "wp-gpios". But this is following what Arnd had
proposed here: http://www.spinics.net/lists/linux-mmc/msg13564.html.

Regarding the MMC_CAP_4_BIT_DATA and MMC_CAP_8_BIT_DATA in your patch,
these can be derived from the bus width information that the driver
receives.

Thanks,
Thomas.
