Subject: [PATCH 2/3] ARM: dts: vf610-colibri: Add PWM support
Date: Wed, 17 Sep 2014 13:46:29 +0530 [thread overview]
Message-ID: <819bd3bc9541ca53f005b7cf95bc890f1a9215e5.1410930820.git.bhuvanchandra.dv@toradex.com> (raw)
In-Reply-To: <cover.1410930820.git.bhuvanchandra.dv@toradex.com>
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.
