Subject: Nokia RX-51: Fix crashing in U-Boot mmc function omap_hsmmc_stop_clock()
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=94f69f4c14cafcce11544d8a615eff3767d66acd;p=u-boot.git

Nokia RX-51: Fix crashing in U-Boot mmc function omap_hsmmc_stop_clock()

After commit 04a2ea248f58 ("mmc: disable UHS modes if Vcc cannot be
switched on and off") U-Boot started crashing on Nokia RX-51 while
initializing mmc and caused reboot loop.

It looks like that some clocks were not enabled and this patch fixes U-Boot
mmc crash.
