Anyway, I think this is redundant with:
commit b30d6958a014812158d9729a3e0b6d448f6e8968
Author: Kuninori Morimoto <kuninori.morimoto.gx@xxxxxxxxxxx>
Date: Sun Aug 24 20:02:16 2014 -0700
mmc: tmio: remove SCLKEN bit setting from tmio_mmc_set_clock()
commit da29fe2bf573f0ae56fdc2e790387cb73fc8c6f8
Author: Shinobu Uehara <shinobu.uehara.xc@xxxxxxxxxxx>
Date: Sun Aug 24 20:03:00 2014 -0700
mmc: tmio: add actual clock support as option
so I will probably just drop it.
