Subject: [PATCH RFC 5/5] ARM: dts: qcom: msm8974-hammerhead: add USB OTG support
Date: Mon,  1 Oct 2018 01:30:05 -0400	[thread overview]
Message-ID: <20181001053005.18906-6-masneyb@onstation.org> (raw)
In-Reply-To: <20181001053005.18906-1-masneyb@onstation.org>

From: Jonathan Marek <jonathan@marek.ca>

Add the device tree bindings for USB OTG support. Driver was tested
using on a LG Nexus 5 (hammerhead) phone.

See my cover letter for a question about how I can convert this patch
over to use a gpio-hog to get rid of the otg-en-gpios property.
