From mboxrd@z Thu Jan 1 00:00:00 1970 From: dianders@chromium.org (Doug Anderson) Date: Tue, 29 Jul 2014 16:24:31 -0700 Subject: [PATCH 1/3] ARM: dts: Turn on USB host vbus on rk3288-evb In-Reply-To: <1406676273-20701-1-git-send-email-dianders@chromium.org> References: <1406676273-20701-1-git-send-email-dianders@chromium.org> Message-ID: <1406676273-20701-2-git-send-email-dianders@chromium.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.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.
