1 | USB EHCI controllers |
2 | ||
3 | Required 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. | |
10 | If device registers are implemented in big endian mode, the device | |
11 | node should have "big-endian-regs" property. | |
12 | If controller implementation operates with big endian descriptors, | |
13 | "big-endian-desc" property should be specified. | |
14 | If both big endian registers and descriptors are used by the controller | |
15 | implementation, "big-endian" property can be specified instead of having | |
16 | both "big-endian-regs" and "big-endian-desc". | |
17 | ||
18 | Example (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 | }; |
