[PATCH v4 09/13] drm/msm/dp: Don't enable HPD interrupts for edp
From: Bjorn Andersson
Date: Mon Dec 05 2022 - 12:45:37 EST
From: Bjorn Andersson <bjorn.andersson@xxxxxxxxxx>
Most instances where HPD interrupts are masked and unmasked are guareded
by the presence of an EDP panel being connected, but not all. Extend
this to cover the last few places, as HPD interrupt handling is not used
for the EDP case.
