Many of the Qualcomm development boards feature DRD capable type-c ports. However these boards differ from smartphones in their usage, and it's generally preferred that they would enter host mode by default when given the choice. This doesn't affect connection to a host-only PC, since the controller is still DRD capable. The RB1/2 are a special case, since they feature an on-board USB hub and a manual dip switch to toggle between it and the type-c port. Preferring host mode offers a useful hint to the software if it doesn't feature a fully DRD capable USB controller driver, it can just use the default mode (rather than defaulting to peripheral mode unconditionally). --- Caleb Connolly (3): arm64: dts: qcom: sm8650: move usb-role-switch to sm8650.dtsi arm64: dts: qcom: sm8350: move usb-role-switch to sm8350.dtsi arm64: dts: qcom: prefer host mode on dev boards arch/arm64/boot/dts/qcom/qcs6490-rb3gen2.dts | 1 + arch/arm64/boot/dts/qcom/qrb2210-rb1.dts | 4 ++++ arch/arm64/boot/dts/qcom/qrb4210-rb2.dts | 4 ++++ arch/arm64/boot/dts/qcom/sm8150-hdk.dts | 1 + arch/arm64/boot/dts/qcom/sm8350-hdk.dts | 3 +-- arch/arm64/boot/dts/qcom/sm8350.dtsi | 1 + arch/arm64/boot/dts/qcom/sm8450-hdk.dts | 1 + arch/arm64/boot/dts/qcom/sm8550-hdk.dts | 4 ++++ arch/arm64/boot/dts/qcom/sm8550-mtp.dts | 4 ++++ arch/arm64/boot/dts/qcom/sm8550-qrd.dts | 4 ++++ arch/arm64/boot/dts/qcom/sm8650-hdk.dts | 3 +-- arch/arm64/boot/dts/qcom/sm8650-mtp.dts | 3 +-- arch/arm64/boot/dts/qcom/sm8650-qrd.dts | 3 +-- arch/arm64/boot/dts/qcom/sm8650.dtsi | 1 + 14 files changed, 29 insertions(+), 8 deletions(-) --- change-id: 20240624-b4-rb2-fixes-1ad33cd72f3a base-commit: f76698bd9a8ca01d3581236082d786e9a6b72bb7 // Caleb (they/them)
