6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Gabor Juhos <j4g8y7@xxxxxxxxx>
[ Upstream commit 47b3e2f3914ae5e8d9025d65ae5cffcbb54bc9c3 ]
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.
