^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 26) Example:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 27) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 28) 	hsusb1_phy {
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 29) 		compatible = "usb-nop-xceiv";

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 37) 		#phy-cells = <0>;
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 38) 	};

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 40) hsusb1_phy is a NOP USB PHY device that gets its clock from an oscillator
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 41) and expects that clock to be configured to 19.2MHz by the NOP PHY driver.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 42) hsusb1_vcc_regulator provides power to the PHY and GPIO 7 controls RESET.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 43) GPIO 13 detects VBus insertion, and accordingly notifies the vbus-regulator.
