4 - compatible : should be "generic-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.
12 - big-endian-regs : boolean, set this for hcds with big-endian registers
13 - big-endian-desc : boolean, set this for hcds with big-endian descriptors
14 - big-endian : boolean, for hcds with big-endian-regs + big-endian-desc
15 - needs-reset-on-resume : boolean, set this to force EHCI reset after resume
16 - has-transaction-translator : boolean, set this if EHCI have a Transaction
17 Translator built into the root hub.
18 - clocks : a list of phandle + clock specifier pairs. In case of Renesas
20 - if a host only channel: first clock should be host.
21 - if a USB DRD channel: first clock should be host and second one
23 - phys : see usb-hcd.txt in the current directory
24 - resets : phandle + reset specifier pair
26 additionally the properties from usb-hcd.txt (in the current directory) are
29 Example (Sequoia 440EPx):
31 compatible = "ibm,usb-ehci-440epx", "usb-ehci";
32 interrupt-parent = <&UIC0>;
34 reg = <0 e0000300 90 0 e0000390 70>;
38 Example (Allwinner sun4i A10 SoC):
40 compatible = "allwinner,sun4i-a10-ehci", "generic-ehci";
41 reg = <0x01c14000 0x100>;
43 clocks = <&ahb_gates 1>;
