Subject: [PATCH 3/3] ARM: dts: colibri-imx6ull: disable runtime pm
Date: Fri, 10 Jul 2020 17:49:34 +0200	[thread overview]
Message-ID: <20200710154935.697190-3-philippe.schenker@toradex.com> (raw)
In-Reply-To: <20200710154935.697190-1-philippe.schenker@toradex.com>

The Colibri iMX6ULL has a somewhat special hardware design due to some
legacy decisions regarding USB OTG. This leads to different issues
when runtime PM is enabled.

Disable runtime power management on colibri-imx6ull USB.
