Subject: mmc: tmio: sdhi: Configure DT2FF register for HS400 mode
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=261445dfafdce252f91fea16517aba5830dd1930;p=u-boot.git

mmc: tmio: sdhi: Configure DT2FF register for HS400 mode

The DT2FF register must be configured differently for HS400 mode
and for HS200/SDR104 mode. Configure the DT2FF register according
to the recommended datasheet settings for each mode.
