There are two events that signal a real change of the link state: HPD going high means the sink is newly connected or wants the source to re-read the EDID, RX sense going low is a indication that the link has been disconnected. Ignore the other two events that also trigger interrupts, but don't need immediate attention: HPD going low does not necessarily mean the link has been lost and should not trigger a immediate read of the status. RX sense going high also does not require a detect cycle, as HPD going high is the right point in time to read the EDID.
