Please apply this on the top of:
"[PATCH v6 00/12] Add support to Odroid U3/X2"
This change only one of MPLL divider and set the MPLL clock to 880.
But such MPLL freq makes some other clocks issue.
In u-boot, the dw mmc driver sets wrong clock(probably some bug) and the
emmc r/w performance is lower than before.
Kernel is booting the same as before. But most of clock values are not
integers now.
I am not sure that everything will work fine.
Can you test in on your kernel?
Thank you,
