Subject: [PATCH v2 1/9] dt-bindings: ufs: Add #reset-cells for Qualcomm controllers
Date: Wed, 23 Jan 2019 14:11:29 -0800 [thread overview]
Message-ID: <20190123221137.41722-2-evgreen@chromium.org> (raw)
In-Reply-To: <20190123221137.41722-1-evgreen@chromium.org>
Enable Qualcomm UFS controllers to expose the PHY reset via a reset
controller.
Signed-off-by: Evan Green <evgreen@chromium.org>
