Revision 713456db179356c6b32a50ea1910fc509615c457 authored by Russell King on 03 March 2014, 14:09:36 UTC, committed by Russell King on 26 June 2014, 10:01:51 UTC
One of Jean-Francois patches changed the EDID polling to once every 10ms for 10 interations, whereas the original code did 1ms for 100 interations. This appears to cause boot-time detection to take noticably longer. Revert this change. Acked-by: Jean-Francois Moine <moinejf@free.fr> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
