| 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. |
| - 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 */>; |
| }; |
