Use "ARM:" instead of "arm:" in patch subject please.

Sort the node alphabetically. IOW, it should be put right before &fec0.

The line is too long. You can split it like:
clocks = <&clks VF610_CLK_IPG_BUS>,
<&clks VF610_CLK_PLATFORM_BUS>,
<&clks VF610_CLK_ESDHC1>;

This property can be dropped, since you have it in board dts.
