From: Roja Rani Yarubandi <redacted> Uart5 is treated as dedicated debug uart.Change the compatible as "qcom,geni-uart" in SoC DT to make it generic and later update it as "qcom,geni-debug-uart" in sc7280-idp Add interconnects and power-domains. Split the pinctrl functions and correct the gpio pins.
