Subject: [PATCH] ARM: dts: imx6dl-yapp4: Specify USB overcurrent protection polarity
Date:   Wed, 15 Jan 2020 16:17:28 +0100
Message-Id: <1579101448-7247-1-git-send-email-michal.vokac@ysoft.com>

Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

After reset the oc protection polarity is set to active high on imx6.
If the polarity is not specified in device tree it is not changed.

The imx6dl-yapp4 platform uses an active-low oc signal so explicitly
configure that in the device tree.
