Subject: [PATCH] drm/msm/dp: Shorten SETUP timeout
Date: Mon, 4 Oct 2021 19:37:50 -0700 [thread overview]
Message-ID: <20211005023750.2037631-1-bjorn.andersson@linaro.org> (raw)
Found in the middle of a patch from Sankeerth was the reduction of the
INIT_SETUP timeout from 10s to 100ms. Upon INIT_SETUP timeout the host
is initalized and HPD interrupt start to be serviced, so in the case of
eDP this reduction improves the user experience dramatically - i.e.
removes 9.9s of bland screen time at boot.
