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 */>; };
