add event thread to execute events serially from event queue. Also timeout mode is supported which allow an event be deferred to be executed at later time. Both link and phy compliant tests had been done successfully. Changes in v2: -- Fix potential deadlock by removing redundant connect_mutex -- Check and enable link clock during modeset -- Drop unused code and fix function prototypes. -- set sink power to normal operation state (D0) before DPCD read Changes in v3: -- push idle pattern at main link before timing generator off -- add timeout handles for both connect and disconnect Changes in v4: -- add ST_SUSPEND_PENDING to handles suspend/modeset test operations -- clear dp phy aux interrupt status when ERR_DPPHY_AUX error -- send segment addr during edid read -- clear bpp depth before MISC register write Changes in v5: -- add ST_SUSPENDED to fix crash at resume Changes in v6: -- at msm_dp_display_enable() do not return until resume_done to avoid kms commit timeout Signed-off-by: Kuogee Hsieh <khsieh@codeaurora.org> Signed-off-by: Rob Clark <robdclark@chromium.org>
