Hm. I've just tried to keep original style in this particular dts.
Want to ack patch below?

What is prefered style of <&label> vs. < &label > usage, btw?

arch/powerpc/boot/dts$ grep "<&" -r . | wc -l
327
arch/powerpc/boot/dts$ grep "< &" -r . | wc -l
92

I can only guess - the first?

Which one? pio-map for spi? This is GPIO pins configuration, to use
dedicated functions (SPI) for these pins, otherwise SPI will not work.

p.s. mpc8272ads.dts is broken wrt spaces/tabs, very.

There should be whitespace after labels.
