Subject: [PATCH v2 08/11] phy: phy-mtk-tphy: make the ref clock optional
Date: Fri, 30 Aug 2019 15:14:55 +0800	[thread overview]
Message-ID: <1567149298-29366-8-git-send-email-chunfeng.yun@mediatek.com> (raw)
In-Reply-To: <1567149298-29366-1-git-send-email-chunfeng.yun@mediatek.com>

Sometimes the reference clock of USB3 PHY comes from oscillator
directly, and no need refer to a fixed-clock in DTS anymore
if make it optional.
