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 - interrupt-parent : interrupt source phandle. 10 - fsl,fullspeed-clock : specifies the full speed USB clock source: 11 "none": clock source is disabled 12 "brg1" through "brg16": clock source is BRG1-BRG16, respectively 13 "clk1" through "clk24": clock source is CLK1-CLK24, respectively 14 - fsl,lowspeed-clock : specifies the low speed USB clock source: 15 "none": clock source is disabled 16 "brg1" through "brg16": clock source is BRG1-BRG16, respectively 17 "clk1" through "clk24": clock source is CLK1-CLK24, respectively 18 - hub-power-budget : USB power budget for the root hub, in mA. 19 - gpios : should specify GPIOs in this order: USBOE, USBTP, USBTN, USBRP, 20 USBRN, SPEED (optional), and POWER (optional). 21 22 Example: 23 24 usb@6c0 { 25 compatible = "fsl,mpc8360-qe-usb", "fsl,mpc8323-qe-usb"; 26 reg = <0x6c0 0x40 0x8b00 0x100>; 27 interrupts = <11>; 28 interrupt-parent = <&qeic>; 29 fsl,fullspeed-clock = "clk21"; 30 gpios = <&qe_pio_b 2 0 /* USBOE */ 31 &qe_pio_b 3 0 /* USBTP */ 32 &qe_pio_b 8 0 /* USBTN */ 33 &qe_pio_b 9 0 /* USBRP */ 34 &qe_pio_b 11 0 /* USBRN */ 35 &qe_pio_e 20 0 /* SPEED */ 36 &qe_pio_e 21 0 /* POWER */>; 37 };
