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
