From mboxrd@z Thu Jan 1 00:00:00 1970 From: Roger Quadros Subject: [PATCH v3 03/10] ARM: dts: dra7-evm: Add CAN support Date: Tue, 4 Nov 2014 12:48:47 +0200 Message-ID: <1415098134-26405-4-git-send-email-rogerq@ti.com> References: <1415098134-26405-1-git-send-email-rogerq@ti.com> Mime-Version: 1.0 Content-Type: text/plain Return-path: In-Reply-To: <1415098134-26405-1-git-send-email-rogerq@ti.com> Sender: linux-can-owner@vger.kernel.org To: tony@atomide.com Cc: wg@grandegger.com, mkl@pengutronix.de, wsa@the-dreams.de, mugunthanvnm@ti.com, george.cherian@ti.com, balbi@ti.com, nsekhar@ti.comnm@ti.com, sergei.shtylyov@cogentembedded.com, linux-omap@vger.kernel.org, linux-can@vger.kernel.org, devicetree@vger.kernel.org, Roger Quadros List-Id: devicetree@vger.kernel.org The board has 2 CAN ports but only the first one can be used. Enable the first CAN port. WAKEUP0 pin doesn't have INPUT enable bit so we just disable weak PULLs. The second CAN port cannot be used without hardware modification so we don't enable the second port.
