[PATCH 1/2] ARM: dts: vf-colibri: split PWM pinctrl

From: Stefan Agner
Date: Wed Dec 02 2015 - 17:11:03 EST


Split PWM pins into separate pinctrl nodes to allow overrides which
select pins individually. This is useful for carrier boards which use
only one pin for PWM and would like to use the other pin for a
different purpose.
