From mboxrd@z Thu Jan 1 00:00:00 1970 From: Ying.Liu@freescale.com (Liu Ying) Date: Thu, 12 Feb 2015 14:01:31 +0800 Subject: [PATCH RFC v9 08/20] ARM: dts: imx6qdl: Move existing MIPI DSI ports into a new 'ports' node In-Reply-To: <1423720903-24806-1-git-send-email-Ying.Liu@freescale.com> References: <1423720903-24806-1-git-send-email-Ying.Liu@freescale.com> Message-ID: <1423720903-24806-9-git-send-email-Ying.Liu@freescale.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org The MIPI DSI node contains some ports which represent possible DRM CRTCs it can connect with. Each port has a 'reg' property embedded. This property will be wrongly interpretted by the MIPI DSI bus driver, because the driver will take each subnode which contains a 'reg' property as a DSI peripheral device. This patch moves the existing MIPI DSI ports into a new 'ports' node so that the MIPI DSI bus driver may distinguish its DSI peripheral device(s) from the existing ports.
