[PATCH] phy: qcom: m31: match requested regulator name with dt schema

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


According to the 'qcom,ipq5332-usb-hsphy.yaml' schema, the 5V
supply regulator must be defined via the 'vdd-supply' property.
The driver however requests for the 'vdda-phy' regulator which
results in the following message when the driver is probed on
a IPQ5018 based board with a device tree matching to the schema:

  qcom-m31usb-phy 5b000.phy: supply vdda-phy not found, using dummy regulator
  qcom-m31usb-phy 5b000.phy: Registered M31 USB phy

This means that the regulator specified in the device tree never
gets enabled.

Change the driver to use the 'vdd' name for the regulator as per
defined in the schema in order to ensure that the corresponding
regulator gets enabled.
