From mboxrd@z Thu Jan 1 00:00:00 1970 From: Randy Li Subject: [PATCH RFC] ARM: dts: samsung: add rga-lvds panel in itop elite Date: Tue, 30 Aug 2016 06:50:02 +0800 Message-ID: <1472511002-9019-1-git-send-email-ayaka@soulik.info> Return-path: Sender: linux-kernel-owner@vger.kernel.org To: devicetree@vger.kernel.org Cc: mark.rutland@arm.com, linux@armlinux.org.uk, kgene@kernel.org, krzk@kernel.org, linux-arm-kernel@lists.infradead.org, linux-samsung-soc@vger.kernel.org, linux-kernel@vger.kernel.org, inki.dae@samsung.com, jy0922.shim@samsung.com, kyungmin.park@samsung.com, dri-devel@lists.freedesktop.org, Randy Li List-Id: devicetree@vger.kernel.org It is actually a lvds panel connected through a rga-lvds bridge. But I really have no idea about what does a port mean in fimd node. Also how should I configure this panel size? I think the i2c found on the panel schematic, but it more likely to be used a touch screen touth. Also the touch screen is not supported in currently driver.
