I've just realized that I had submitted practically the same change
(excluding iMX specifics) and about the same time in October 2014, but
my v1 is one and a half hours later than yours preceding v6 :)

Since I've subscribed to the linux-pwm right before sending my changes,
I don't have your changes in my mailbox. Would you mind to review my
v3 "pwm: support backward compatibility of DTB extending PWM args":

   http://lists.infradead.org/pipermail/linux-arm-kernel/2014-November/303833.html

then incorporate anything you find useful into your series and resend
v7? Or just resend the rebased v6 if nothing is found attracting?

In my turn I'll spend time to review the series and test it on iMX.
