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@xxxxxxxxxx --- 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@xxxxxxxxxxx --- Bjorn Andersson (6): arm64: dts: qcom: sc7280: Enable MDP turbo mode arm64: dts: qcom: qcs6490-rb3gen2: Add DP output arm64: dts: qcom: qcs6490-rb3gen2: Enable adsp and cdsp arm64: dts: qcom: qcs6490-rb3gen2: Introduce USB redriver arm64: dts: qcom: qcs6490-rb3gen2: Enable USB Type-C display arm64: defconfig: Enable sc7280 display and gpu clock controllers arch/arm64/boot/dts/qcom/qcs6490-rb3gen2.dts | 171 ++++++++++++++++++++++++++- arch/arm64/boot/dts/qcom/sc7280.dtsi | 5 + arch/arm64/configs/defconfig | 2 + 3 files changed, 177 insertions(+), 1 deletion(-) --- base-commit: f27830a6a17b722f9dbbccfaae1f3bae8700c672 change-id: 20240209-rb3gen2-dp-connector-bddfb892ff20 Best regards, -- Bjorn Andersson <quic_bjorande@xxxxxxxxxxx>
