Subject: mmc: mtk-sd: fix sclk cycles shift value
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=f875a1257800b5f60d8e8138a649a54ebfa3c5cf;p=u-boot.git

mmc: mtk-sd: fix sclk cycles shift value

It turns out that the sclk cycles used by mt7620/mt7628 is the same as
other chips (20 bits, 1048576), not 65536.

This patch removes sclk_cycle_shift from dev_comp, and uses a macro with
a value 20 instead.
