This patch set cleans up DP detection logic to bring all DPCD operations at one place and to create a clear demarcation between handling of long and short pulses. This simplifies fixing of sink count related detection for DP panels. Patches: 1. First two patches clean up intel_dp_detect and form a new function which will include all DPCD related operations. 2. Second patch splits up intel_dp_check_link_status to form a new function which will handle short pulse requests. 3. Last three patches fixes the detection logic related to sink count i.e detect changes in sink count and handle them appropriately. Note: this is tested on BXT with non-mst panels, will get back ASAP with results for MST panels too.
