From 9dac73a4ec2c0a791bbfc6630dc4629ce11e68b9 Mon Sep 17 00:00:00 2001 From: Daniel R Thompson Date: Mon, 26 Jun 2006 00:27:00 -0700 Subject: [PATCH] fbdev: tag by scantype in sysfs Modify the sysfs description of a video mode such that modes are tagged with their scan type, (p)rogessive, (i)nterlaced, (d)ouble scan. For example, U:1920x1080i-50. This is useful to disambiguate some of the 'consumer' video timings found in CEA-861 (especially those for EDTV).
