Well, it certainly looks implemented now (the clock parent for ehci and ohci is clock-controller@2001000, which is "allwinner,sun20i-d1-ccu”, which is sun20i_d1_ccu.c, it looks like it has everything needed, although I suppose it certainly possible that the clock/reset index constants used in the code doesn't match what the device tree is using; always a danger).
