[v2,1/4] arm64: boot: dts: qcom: sm8150: Add nodes for PMIC based typec detection

Commit Message

Wesley Cheng Oct. 9, 2020, 8:28 a.m. UTC

Introduce required child nodes to enable the PMIC based USB type C driver.
This consits of connector and endpoint nodes to drivers, which manage the
type C mux and the USB role switch.
