There is a reason to use a different compatible string for Exynos4210
rev0. The PWM block is used as a timer there, while on newer revs MCT is
used. Sorry, but I have to NAK this patch.
As I explained in my reply to patch 11/17, I'd suggest keeping the PWM
drivers as is, because there is no need to remove support for DT
compatible strings.
Best regards,
Tomasz
