IMO, patches should always have a non-empty changelog.  Even if it is 
relatively trivial.  The same comment applies to several other patches 
in this series.

Does this need to enable CONFIG_USB_EHCI_HCD_PLATFORM is some 
defconfig file, like you did with the MIPS Loongson 1B?

And likewise for quite a few of the other patches in this series.

Don't you need to change/set the pdev name also?  Likewise for patch 
20/25 and 24/25.
