[PATCH v2 0/2] arm64: dts: qcom: sc8280xp-microsoft-blackrock: DP audio + 4-lane altmode

[Jens Glathe via B4 Relay]

This series contains some well-tested improvements for the Windows Dev
Kit 2023 (Blackrock).

Patch 1 is for enabling audio via DisplayPort outputs (DP0..DP2).

Patch 2 enables full 4-lane DP altmode on the USB-C ports and the
mini-DP connector. It's the same treatment that was previously done 
for the X13s.

Related (still pending) fix that makes DP altmode on USB0 work in both
orientations on that port:
