Subject: [PATCH 2/9] phy: qcom-qusb2: Add support for SDM630/660
Date:   Sun, 26 Jul 2020 13:11:59 +0200
Message-Id: <20200726111215.22361-3-konradybcio@gmail.com>
In-Reply-To: <20200726111215.22361-1-konradybcio@gmail.com>

Precedence: bulk

QUSB on these SoCs actually uses *almost* the same
configuration that msm8996 does, so we can reuse
the phy_cfg from there with just a single change
(se clock scheme).
