Subject: [PATCH v2 5/5] scsi: ufs-mediatek: Allow unbound mphy
Date: Fri, 29 May 2020 17:23:10 +0800 [thread overview]
Message-ID: <20200529092310.1106-6-stanley.chu@mediatek.com> (raw)
In-Reply-To: <20200529092310.1106-1-stanley.chu@mediatek.com>
Allow unbound MPHY module since not every MediaTek UFS platform
needs specific MPHY control.
