[PATCH 00/14] drm/i915/tc: Fix a few TypeC / MST issues

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

 



This patchset fixes a few issues on TypeC ports, related to the legacy
port handling, HW state readout/verification. It also fixes an issue on
TC port/MST outputs during system suspend/resume, where the modeset
restoring the pre-suspend state fails atm.

Tested on ICL, TGL, ADLP.
