[PATCH] fbdev: tag by scantype in sysfs (9dac73a4) · Commits · 戴 / test

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). Signed-off-by:
