[PATCH v1] drm/msm/dp: use dp_hpd_plug_handle() and dp_hpd_unplug_handle() directly

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



For internal HPD case, hpd_event_thread is created to handle HPD
interrupts generated by HPD block of DP controller. It converts
HPD interrupts into events and executed them under hpd_event_thread
context. For external HPD case, HPD events is delivered by way of
dp_bridge_hpd_notify() under thread context. Since they are executed
under thread context already, there is no reason to hand over those
events to hpd_event_thread. Hence dp_hpd_plug_handle() and
dp_hpd_unplug_hanlde() are called directly at dp_bridge_hpd_notify().
