+Subject: [PATCH 2/3] drm/i915: Increase LSPCON timeout
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+100 ms is not enough time for the LSPCON adapter on Intel NUC devices to
+settle. This causes dropped display modes at boot or screen reconfiguration.
+Empirical testing can reproduce the error up to a timeout of 190 ms. Basic
+boot and stress testing at 200 ms has not (yet) failed.
+
+Increase timeout to 400 ms to get some margin of error.
+
+Changes from v1:
+The initial suggestion of 1000 ms was lowered due to concerns about delaying
+valid timeout cases.
+Update patch metadata.
+
+Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=107503
+Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1570392
