From 8768a52f8f53e6f54bce77faade1007d4142fa7c Mon Sep 17 00:00:00 2001 From: Tomi Valkeinen Date: Thu, 6 Sep 2012 13:57:39 +0300 Subject: [PATCH] OMAPDSS: omap_dss_register_device() doesn't take display index We used to have all the displays of the board in one list, and we made a "displayX" directory in the sysfs, where X was the index of the display in the list. This doesn't work anymore with device tree, as there's no single list to get the number from, and it doesn't work very well even with non-DT as we need to do some tricks to get the index nowadays. This patch changes omap_dss_register_device() so that it doesn't take disp_num as a parameter anymore, but uses a private increasing counter for the display number.
