From 5d529c7e90a675be13af95508efb6eb93da9345c Mon Sep 17 00:00:00 2001 From: Fabio Estevam Date: Tue, 8 Oct 2013 15:52:12 -0300 Subject: [PATCH 58/59] ARM: dts: imx51-babbage: Make DVI and WVGA panel functional Currently we get the following errors on imx51-babbage: /display@di0: could not find display-timings node /display@di0: no timings specified /display@di1: could not find display-timings node /display@di1: no timings specified imx-drm imx-drm: failed to allocate buffer with size 0 Provide timing values for IPU1, which is connected to a DVI bridge and to IPU2, which can be connected to the WVGA panel, so that both of them can be functional. While at it, disable the WVGA panel, so that DVI output becomes the default one.
