[PATCH V7 4/7] arm64: dts: sc7280: Update QUPv3 UART5 DT node

From: Rajesh Patil
Date: Fri Sep 03 2021 - 00:30:00 EST


From: Roja Rani Yarubandi <rojay@xxxxxxxxxxxxxx>

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.
