The Colibri standard defines four pins as PWM outputs, two of them (PWM
A and C) are routed to FTM instance 0 and the other two (PWM B and D)
are routed to FTM instance 1. Hence enable both FTM instances for the
Colibri module and mux the four pins accordingly.

You should add Stefan's ACK tag.

I was trying to apply the patches, but found pwm1 is not available in
vf610.dtsi at all. What tree is your patch generated against? Or did I
miss any prerequisite patches?

Yes, I guess for some reason he dropped that one from v3:
