[PATCH v2 3/4] drm/bridge: tfp410: Fix logic to configured polled HPD

From: Jonathan Cormier
Date: Thu Jan 26 2023 - 17:41:02 EST


From: Michael Williamson <michael.williamson@xxxxxxxxxxxxxxxx>

The logic to configure polling (vs async/irq notification) of hot-plug
events was not correct. If the connected bridge requires polling,
then inform the upstream bridge we also require polling.
