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?

For any prerequisite patches that haven't been applied, you should
either include it in your series or mention the dependency in the cover
letter.

For this thime, I just picked the prerequisite and applied these two
with Stefan's ACK.

One prerequisite patch(PATCH 1/3) was missed. Available over here:
