Should this also list "brcm,kona-pwm" as compatible? From patch
1, it sounds like that was the original one.

Arnd,
The NSP is a iProc based SoC and the pwm controller register offsets are
slightly differ with the kona pwm controller. The compatible will be either
"brcm,kona-pwm" or "brcm,iproc-pwm".
