[Intel-gfx] [PATCH 4/8] drm/i915/icl: implement the tc/legacy HPD {dis, }connect flow for DP

2018-07-11 Thread Paulo Zanoni
Implement the DFLEXDPPMS/DFLEXDPCSSS dance for DisplayPort. These functions need to be called during HPD assert/deassert, but due to how our driver works it's much simpler if we always call them when icl_digital_port_connected() is called, which means we won't call them exactly once per HPD event.
