Kernel-3.10.0-957.el7_usb

Freescale QUICC Engine USB Controller

Required properties:

• compatible : should be “fsl,-qe-usb”, “fsl,mpc8323-qe-usb”.
• reg : the first two cells should contain usb registers location and
  length, the next two two cells should contain PRAM location and
  length.
• interrupts : should contain USB interrupt.
• interrupt-parent : interrupt source phandle.
• fsl,fullspeed-clock : specifies the full speed USB clock source:
  “none”: clock source is disabled
  “brg1” through “brg16”: clock source is BRG1-BRG16, respectively
  “clk1” through “clk24”: clock source is CLK1-CLK24, respectively
• fsl,lowspeed-clock : specifies the low speed USB clock source:
  “none”: clock source is disabled
  “brg1” through “brg16”: clock source is BRG1-BRG16, respectively
  “clk1” through “clk24”: clock source is CLK1-CLK24, respectively
• hub-power-budget : USB power budget for the root hub, in mA.
• gpios : should specify GPIOs in this order: USBOE, USBTP, USBTN, USBRP,
  USBRN, SPEED (optional), and POWER (optional).

Example:

usb@6c0 {
compatible = “fsl,mpc8360-qe-usb”, “fsl,mpc8323-qe-usb”;
reg = <0x6c0 0x40 0x8b00 0x100>;
interrupts = <11>;
interrupt-parent = <&qeic>;
fsl,fullspeed-clock = “clk21”;
gpios = <&qe_pio_b 2 0 /* USBOE */
&qe_pio_b 3 0 /* USBTP */
&qe_pio_b 8 0 /* USBTN */
&qe_pio_b 9 0 /* USBRP */
&qe_pio_b 11 0 /* USBRN */
&qe_pio_e 20 0 /* SPEED */
&qe_pio_e 21 0 /* POWER */>;
