Subject: [PATCH 0/2] *** fix missing unplug interrupt problem ***
Date: Thu, 7 Jan 2021 12:30:23 -0800 [thread overview]
Message-ID: <1610051425-20632-1-git-send-email-khsieh@codeaurora.org> (raw)
In-Reply-To: <y>
Both AUX_SW_RESET and DP_SW_RESET clear pending HPD interrupts.
Therefore irq_hpd handler should not issues either aux or sw reset
to avoid following unplug interrupt be cleared accidentally.

drm/msm/dp: postpone irq_hpd event during connection pending state
drm/msm/dp: unplug interrupt missed after irq_hpd handler
