1USB EHCI controllers 2 3Required properties: 4 - compatible : should be "usb-ehci". 5 - reg : should contain at least address and length of the standard EHCI 6 register set for the device. Optional platform-dependent registers 7 (debug-port or other) can be also specified here, but only after 8 definition of standard EHCI registers. 9 - interrupts : one EHCI interrupt should be described here. 10If device registers are implemented in big endian mode, the device 11node should have "big-endian-regs" property. 12If controller implementation operates with big endian descriptors, 13"big-endian-desc" property should be specified. 14If both big endian registers and descriptors are used by the controller 15implementation, "big-endian" property can be specified instead of having 16both "big-endian-regs" and "big-endian-desc". 17 18Example (Sequoia 440EPx): 19 ehci@e0000300 { 20 compatible = "ibm,usb-ehci-440epx", "usb-ehci"; 21 interrupt-parent = <&UIC0>; 22 interrupts = <1a 4>; 23 reg = <0 e0000300 90 0 e0000390 70>; 24 big-endian; 25 }; 26
