From mboxrd@z Thu Jan 1 00:00:00 1970 From: Doug Anderson Subject: [PATCH v2 1/3] ARM: dts: Turn on USB host vbus on rk3288-evb Date: Wed, 30 Jul 2014 13:00:10 -0700 Message-ID: <1406750412-15592-2-git-send-email-dianders@chromium.org> References: <1406750412-15592-1-git-send-email-dianders@chromium.org> Return-path: In-Reply-To: <1406750412-15592-1-git-send-email-dianders@chromium.org> Sender: linux-kernel-owner@vger.kernel.org To: Heiko Stuebner , Kever Yang Cc: Sonny Rao , Arnd Bergmann , linux-arm-kernel@lists.infradead.org, linux-usb@vger.kernel.org, sergei.shtylyov@cogentembedded.com, Doug Anderson , robh+dt@kernel.org, pawel.moll@arm.com, mark.rutland@arm.com, ijc+devicetree@hellion.org.uk, galak@codeaurora.org, linux@arm.linux.org.uk, devicetree@vger.kernel.org, linux-kernel@vger.kernel.org List-Id: devicetree@vger.kernel.org There is no phy driver that works on the Rockchip board for either USB host port yet. For now just hardcode the vbus signal to be on all the time which makes both the dwc2 host and the EHCI port work.
