Kernel-4.18.0-80.el8_lpc32xx-udc

• NXP LPC32xx SoC USB Device Controller (UDC)

Required properties:

• compatible: Must be “nxp,lpc3220-udc”
• reg: Physical base address of the controller and length of memory mapped
  region.
• interrupts: The USB interrupts:

          * USB Device Low Priority Interrupt
          * USB Device High Priority Interrupt
          * USB Device DMA Interrupt
          * External USB Transceiver Interrupt (OTG ATX)
  

• transceiver: phandle of the associated ISP1301 device - this is necessary for

           the UDC controller for connecting to the USB physical layer
  

Example:

isp1301: usb-transceiver@2c {
    compatible = "nxp,isp1301";
    reg = <0x2c>;
};

usbd@31020000 {
    compatible = "nxp,lpc3220-udc";
    reg = <0x31020000 0x300>;
    interrupt-parent = <&mic>;
    interrupts = <0x3d 0>, <0x3e 0>, <0x3c 0>, <0x3a 0>;
    transceiver = <&isp1301>;
};
