Subject: [PATCH v2 1/4] phy: rockchip: inno-usb2: Add usb2 phy support for RK3368
Date: Tue, 9 Sep 2025 21:29:55 +0800 [thread overview]
Message-ID: <20250909132958.26423-2-cn.liweihao@gmail.com> (raw)
In-Reply-To: <20250909132958.26423-1-cn.liweihao@gmail.com>
RK3368 has one USB2.0 PHY with two ports. This adds device specific data
for it. Device specific data get form rockchip downstream source [1].
