1 Freescale QUICC Engine USB Controller
2
3 Required properties:
4 - compatible : should be "fsl,<chip>-qe-usb", "fsl,mpc8323-qe-usb".
5 - reg : the first two cells should contain usb registers location and
6 length, the next two two cells should contain PRAM location and
7 length.
8 - interrupts : should contain USB interrupt.
9 - fsl,fullspeed-clock : specifies the full speed USB clock source:
10 "none": clock source is disabled
11 "brg1" through "brg16": clock source is BRG1-BRG16, respectively
12 "clk1" through "clk24": clock source is CLK1-CLK24, respectively
13 - fsl,lowspeed-clock : specifies the low speed USB clock source:
14 "none": clock source is disabled
15 "brg1" through "brg16": clock source is BRG1-BRG16, respectively
16 "clk1" through "clk24": clock source is CLK1-CLK24, respectively
17 - hub-power-budget : USB power budget for the root hub, in mA.
18 - gpios : should specify GPIOs in this order: USBOE, USBTP, USBTN, USBRP,
19 USBRN, SPEED (optional), and POWER (optional).

23 usb@6c0 {
24 compatible = "fsl,mpc8360-qe-usb", "fsl,mpc8323-qe-usb";
25 reg = <0x6c0 0x40 0x8b00 0x100>;
26 interrupts = <11>;
27 interrupt-parent = <&qeic>;
28 fsl,fullspeed-clock = "clk21";
29 gpios = <&qe_pio_b 2 0 /* USBOE */
30 &qe_pio_b 3 0 /* USBTP */
31 &qe_pio_b 8 0 /* USBTN */
32 &qe_pio_b 9 0 /* USBRP */
33 &qe_pio_b 11 0 /* USBRN */
34 &qe_pio_e 20 0 /* SPEED */
35 &qe_pio_e 21 0 /* POWER */>;
