Thus the min and max values are corrected and the regulator added as a proper supply for the usb phys. This fixes the following warnings during the probe of the mxs_phy driver: mxs_phy 20c9000.usbphy: supply phy-3p0 not found, using dummy regulator mxs_phy 20ca000.usbphy: supply phy-3p0 not found, using dummy regulator The regulator handling was introduced by commit `966d73152078 (usb: phy: mxs: enable regulator phy-3p0 to improve signal qualilty, 2024-07-26)`.
