Thanks for your mails, I'm just integrating your suggestions.

Yes, still under development. GPIO is subject to an open minor issue
(will post an RFC later), and irq is part of the main mach-lpc32xx dt
switch - I have DT-irq already working, but I need to OF'ize lcd and usb
to complete.

For the LPC32xx specific things, including arch/arm/mach-lpc32xx, I will
switch over to DT quickly, eliminating phy3250.c by replacing with a
respective dts file.

The other subsystems changes (pnx*) can and should be dual DT/non-DT to
support other platforms and users who still use it in a non-DT way.

Yes, sounds reasonable regarding the LPC32xx specific bits like wdt and
adc. Is there sth. I can do about it?

Thanks all,

Roland
