Hi Thierry,

Funny I should hear from you about this today.... I just turned my attention
back to this today and noticed that it never made it into your for-next branch.
 Yes, it is the latest.  If the patch still applies cleanly, please feel free.
Otherwise, I'd be glad to rework it against something more recent.

Also, we never got any ACKs for patch 2/2, which just adds the nodes to
arch/arm/boot/dts/pxa27x.dtsi
Any advice on whom to nudge?

Thanks much!
Mike
