From: Clint Taylor <clinton.a.tay...@intel.com>
Current 50ms max threshold timing for an EDID read is very close to the
actual time for a 2 block HDMI EDID read of 48ms. Any delay like a clock
stretch by the EDID eeprom will cause this test to fail. A 4 block HDMI
EDID read takes approximately 88ms under nominal conditions, making the max
threshold 95ms will allow this test to pass regardless of monitor attached.
