Freescale QUICC Engine USB Controller
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible : should be "fsl,<chip>-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 */>;
|
||
|
|
};
