Subject: [PATCH v2 0/6] arm64: dts: qcom: qcs6490-rb3gen2: Enable two
 displays

RB3Gen2 is capable of producing DisplayPort output on a dedicated
mini-DP connector and USB Type-C.

Utilize Abel's work for DP vs eDP selection to allow configuring both
controllers in DP-mode, then enable the two output paths.

Tested by driving fbcon to 4k@60 + 4k@30 concurrently.

Depends on 20240324-x1e80100-display-refactor-connector-v4-0-e0ebaea66a78@...aro.org

---
Changes in v2:
- Rebased on Abel's updated implementation
- Dropped DP driver changes, as Abel's new DP/eDP selection mechanism
  obsoleted these.
- Squashed the two separate patches adding pmic-glink
- Corrected remoteproc firmware-name paths
- Described the mini-DP connector in DT, and hence no longer use the
  internal HPD handler in DP driver
- Link to v1: https://lore.kernel.org/r/20240221-rb3gen2-dp-connector-v1-0-dc0964ef7d96@quicinc.com
