Subject: [PATCH 0/6] arm64: qcom: sm84[34]50: enable DP altmode on USB-C
 Connector

This is the final step to achieve USB-C Altmode on the HDK8350
and HDK8450 now DP controller support, USB3+DP Combo PHY and
pmic glink support have been merged for those platforms.

This patchset depends on the QMP Combo USB3+DP PHY orientation
support at [1].

The following has been successfully tested:
- USB-C PD Power Role, reported status are coherent
- USB-C dual-role data
  - USB2.0 only (no-PD) as DFP or UFP
  - USB2.0 + USB SuperSpeed as DFP or UFP & in both orientations
  - USB2.0 + USB SuperSpeed + DisplayPort Altmode in both orientations
  - DisplayPort-only Altmode in both orientations

Data role and SuperSpeed lanes were correctly switched on the PHY
side after USB-C removal/insertion.
