Sorry for the late reply. I think this is great and I'd like to just apply it.
Can you re-send to arm@...nel.org if you're happy with that?

Looking at your description above, I see that you included pxa168_defconfig
and pxa910_defconfig as well, but they are mach-mmp rather than mach-pxa.
Can you check if that has added in anything we don't want?
