Subject: [PATCH 1/7] drm/msm/dp: use dp_ctrl_off_link_stream during PHY compliance test run
Date: Tue, 6 Jul 2021 10:20:14 -0700 [thread overview]
Message-ID: <1625592020-22658-2-git-send-email-khsieh@codeaurora.org> (raw)
In-Reply-To: <1625592020-22658-1-git-send-email-khsieh@codeaurora.org>
DP cable should always connect to DPU during the entire PHY compliance
testing run. Since DP PHY compliance test is executed at irq_hpd event
context, dp_ctrl_off_link_stream() should be used instead of dp_ctrl_off().
dp_ctrl_off() is used for unplug event which is triggered when DP cable is
dis connected.
