Imre Deak a40ee54e9a drm/i915: Disconnect PHYs left connected by BIOS on disabled ports ... BIOS may leave a TypeC PHY in a connected state even though the corresponding port is disabled. This will prevent any hotplug events from being signalled (after the monitor deasserts and then reasserts its HPD) until the PHY is disconnected and so the driver will not detect a connected sink. Rebooting with the PHY in the connected state also results in a system hang. Fix the above by disconnecting TypeC PHYs on disabled ports. Before commit 64851a32c4 the PHY connected state was read out even for disabled ports and later the PHY got disconnected as a side effect of a tc_port_lock/unlock() sequence (during connector probing), hence recovering the port's hotplug functionality.
