Subject: ARM: dts: vf610-colibri: Add PWM support
X-Git-Tag: firefly_0821_release~176^2~2766^2~10^2~30
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=9c42fa1d94e5b0d0ed11f5b9762a9b7acb1fcf15;p=firefly-linux-kernel-4.4.55.git

ARM: dts: vf610-colibri: Add PWM support

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.
