Configure the Type-C and VBUS regulator on PM7250B and wire it up to the USB PHY, so that USB role and orientation switching works. Signed-off-by: Luca Weiss <luca.weiss@fairphone.com> --- With this patch I'm not quite sure if the 'ports' are connected correctly, though functionally everything appears to work fine. On some other SoCs port@1 in qmpphy and a second port in dwc3 are connected together also - one port of USB 2.0 HS, one for USB 3.0 SS. Here I'm following sm8250's solution. Also checking the binding doc doesn't reveal anything useful. --- arch/arm64/boot/dts/qcom/sm6350.dtsi | 25 ++++++++++ arch/arm64/boot/dts/qcom/sm7225-fairphone-fp4.dts | 57 ++++++++++++++++++++++- 2 files changed, 81 insertions(+), 1 deletion(-)
