So the phrasing should be "compatible: should be among:" ?

Indeed. Currently, they are all the same. By that logic, shouldn't it be
compatible = "marvell,pxa250-pwm", "marvell,pxa270-pwm", "marvell,pxa168-pwm",
"marvell,pxa910-pwm";
I am admittedly fuzzy on device tree, but this is starting to seem strange.
Anyway, I'll defer to your judgement and resubmit if you can give me precise
guidance on the above. Thanks again for the review.
Thanks,
Mike
