Re: [PATCH v2] thunderbolt: Enable hidden DP OUT adapter on Dell TB16 dock

[sashiko-bot@kernel.org]

> The Dell TB16 Thunderbolt 3 dock consists of two Alpine Ridge 4C routers
> in a chain: one in the captive cable module (DROM 00d4:b051 "Dell
> Thunderbolt Cable") and one in the dock itself (DROM 00d4:b054 "Dell
> Thunderbolt Dock"). The dock has four video connectors: mini DisplayPort,
> HDMI, full size DisplayPort and VGA.
> 
> Mini DisplayPort and HDMI sit behind an MST hub on DP OUT adapter 8 of
> the dock router and work fine. Full size DisplayPort and VGA are wired
> to DP OUT adapter 8 of the cable router, but the cable router's DROM
> marks that adapter as disabled. The software connection manager
> therefore never initializes it, never tunnels DisplayPort to it, and a
> monitor on the full size DisplayPort or VGA connector stays dark. Only
> two external displays can be used with the dock, while all of them work
> with the firmware connection manager (and under Windows).
