[PATCH 6/6] mmc: tmio: move mmc_of_parse() out of tmio_mmc_host_probe()
From: Masahiro Yamada
Date: Tue Nov 07 2017 - 03:12:47 EST
mmc_of_parse() parses various DT properties and sets capability flags
accordingly. However, drivers have no chance to run platform init
code depending on such flags because mmc_of_parse() is called from
tmio_mmc_host_probe().
Move mmc_of_parse() out of tmio_mmc_host_probe() so that drivers can
handle capabilities before mmc_add_host().
