Subject: [PATCH v2 7/7] ARM: dts: qcom: msm8974-hammerhead: add USB OTG support
Date: Wed, 31 Oct 2018 20:11:49 -0400 [thread overview]
Message-ID: <20181101001149.13453-8-masneyb@onstation.org> (raw)
In-Reply-To: <20181101001149.13453-1-masneyb@onstation.org>
Add the device tree bindings for USB OTG support. Driver was tested
using on a LG Nexus 5 (hammerhead) phone. This patch is based on work
from Jonathan Marek and from the other msm8974 devices.
