From mboxrd@z Thu Jan 1 00:00:00 1970 From: Leonard Crestez Subject: [PATCH 0/3] ARM: imx: Make DRM_MXSFB and FB_MXS coexist Date: Fri, 15 Jun 2018 22:43:41 +0300 Message-ID: Mime-Version: 1.0 Content-Type: text/plain Return-path: Sender: linux-kernel-owner@vger.kernel.org To: Fabio Estevam , Lucas Stach , Shawn Guo Cc: Pengutronix Kernel Team , NXP Linux Team , Marco Franchi , dri-devel@lists.freedesktop.org, linux-fbdev@vger.kernel.org, linux-arm-kernel@lists.infradead.org, devicetree@vger.kernel.org, linux-kernel@vger.kernel.org List-Id: devicetree@vger.kernel.org Some imx boards have new drm-style bindings for lcdif devices but using them requires rebuilding the kernel with FB_MXS=n DRM_MXSFB=y. It is relatively easy to allow both drivers to coexist by renaming drm/mxsfb to "mxsfb-drm" and making the old fbdev driver return -ENODEV instead of -ENOENT when it fails to find the display node. This makes display on imx6sx-sdb "just work" with both styles of bindings. In order to test the old bindings I locally reverted commit 7caa59e0d40c ("ARM: dts: imx6sx-sdb: Convert from fbdev to drm bindings") Leonard Crestez (3): drm: mxsfb: Change driver.name to mxsfb-drm fbdev: mxsfb: Return ENODEV on missing display node ARM: imx_v6_v7_defconfig: Enable DRM_MXSFB arch/arm/configs/imx_v6_v7_defconfig | 2 ++ drivers/gpu/drm/mxsfb/mxsfb_drv.c | 2 +- drivers/video/fbdev/mxsfb.c | 2 +- 3 files changed, 4 insertions(+), 2 deletions(-) -- 2.17.1
