From 2f2befd820252d05be7b1f5528a57af85338f59c Mon Sep 17 00:00:00 2001 From: Javier Martinez Canillas Date: Tue, 26 Nov 2013 15:03:39 -0800 Subject: ARM: dts: omap3-igep0020: name twl4030 VPLL2 regulator as vdds_dsi On Device Tree boot the VDDS_DSI regulator is not linked to the DPI device so omapfb driver probing fails with: [ 3.186035] OMAPFB: omapfb_probe [ 3.190704] omapdss DPI error: can't get VDDS_DSI regulator [ 3.196594] omapfb omapfb: failed to connect default display [ 3.202667] omapfb omapfb: failed to init overlay connections [ 3.208892] OMAPFB: free_resources [ 3.212493] OMAPFB: free all fbmem [ 3.216735] omapfb omapfb: failed to setup omapfb As a workaround name the VPLL2 regulator from twl4030 as vdds_dsi so getting the VDDS_DSI regulator will succeed on dpi_init_regulator().
