1Freescale QUICC Engine USB Controller 2 3Required 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). 20 21Example: 22 23usb@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 */>; 36}; 37
