Antoine,

I have tentatively applied this to berlin/dt with a small fixup we
discussed on IRC:

uart0/uart1 clock-frequency = <foo>; replaced by clocks = <&smclk>;

For now, as I don't have a non-github repo yet, you'll find the
branches on:

https://github.com/shesselba/linux-berlin.git

There is also a for-next branch that will become be part of linux/next
as soon as I figured out how to request it being pulled.

Sebastian
