Subject: [PATCH v5 5/8] arm64: dts: msm8996: Add UFS PHY reset controller
Date: Thu, 21 Mar 2019 10:17:57 -0700	[thread overview]
Message-ID: <20190321171800.104681-6-evgreen@chromium.org> (raw)
In-Reply-To: <20190321171800.104681-1-evgreen@chromium.org>

Add the reset controller for the UFS controller, and wire it up
so that the UFS PHY can initialize itself without relying on
implicit sequencing between the two drivers.
