From mboxrd@z Thu Jan 1 00:00:00 1970 From: Jagan Teki Subject: [PATCH v3] ARM: dts: rockchip: Add usb host0 ohci node for rk3288 Date: Mon, 20 Jul 2020 16:28:46 +0530 Message-ID: <20200720105846.367776-1-jagan@amarulasolutions.com> Mime-Version: 1.0 Content-Transfer-Encoding: 8bit Return-path: Sender: linux-kernel-owner@vger.kernel.org To: Heiko Stuebner , Rob Herring Cc: Suniel Mahesh , Michael Trimarchi , linux-arm-kernel@lists.infradead.org, linux-rockchip@lists.infradead.org, devicetree@vger.kernel.org, linux-kernel@vger.kernel.org, linux-amarula , Jagan Teki , William Wu List-Id: linux-rockchip.vger.kernel.org rk3288 and rk3288w have a usb host0 ohci controller. Although rk3288 ohci doesn't actually work on hardware, but rk3288w ohci can work well. So add usb host0 ohci node in rk3288 dtsi and the quirk in ohci platform driver will disable ohci on rk3288.
