[PATCH 1/3] dt-bindings: phy: qcom: qmp-combo: add support for vdda-aux regulator

From: Amit Singh
Date: Mon Nov 10 2025 - 06:59:13 EST


Add support for the "vdda-aux" regulator in the QMP PHY binding, with
an enable_load of 36000 µA. Managing this auxiliary rail in the driver
allows proper power configuration on platforms that provide the supply,
improving PHY stability.

This change is a no-op on platforms that do not define the "vdda-aux"
regulator.
