[PATCH v2] arm64: dts: qcom: hamoa-iot-evk: Add vbus regulator support for Type-A ports

From: Krishna Kurapati
Date: Mon Dec 08 2025 - 23:17:22 EST


The Multiport controller on Hamoa EVK platform is connected to Two Type-A
ports. VBUS for each of these ports are provided by a TPS2559QWDRCTQ1
regulator, controlled from PMIC GPIOs.

Add the necessary regulators and GPIO configuration to power these.
