Subject: [PATCH v2 5/5] arm64: dts: rockchip: add USB support to RK3308 dts
Date: Fri, 14 May 2021 17:00:44 +0200 [thread overview]
Message-ID: <20210514150044.2099298-6-t.schramm@manjaro.org> (raw)
In-Reply-To: <20210514150044.2099298-1-t.schramm@manjaro.org>
The Rockchip RK3308 features an integrated USB 2.0 phy, an USB OTG
controller and OHCI/EHCI interfaces.
This patch adds all of those to the RK3308 dtsi and thereby enables USB
support on the RK3308.
