The pinctrl driver for SC7180 has no QUPv3 mux for 51 and 52 GPIOs. I
also tried checking devcfg.mbn of my device using qc-devcfg-parser, but
it printed limited information:

I don't have a dock or a DP-compatible monitor at my disposal.
I found the schematic for these devices and found no wires for DP
altmode.> Konrad
