USB EHCI controllers
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible : should be "generic-ehci".
|
||
|
|
- reg : should contain at least address and length of the standard EHCI
|
||
|
|
register set for the device. Optional platform-dependent registers
|
||
|
|
(debug-port or other) can be also specified here, but only after
|
||
|
|
definition of standard EHCI registers.
|
||
|
|
- interrupts : one EHCI interrupt should be described here.
|
||
|
|
|
||
|
|
Optional properties:
|
||
|
|
- big-endian-regs : boolean, set this for hcds with big-endian registers
|
||
|
|
- big-endian-desc : boolean, set this for hcds with big-endian descriptors
|
||
|
|
- big-endian : boolean, for hcds with big-endian-regs + big-endian-desc
|
||
|
|
- needs-reset-on-resume : boolean, set this to force EHCI reset after resume
|
||
|
|
- has-transaction-translator : boolean, set this if EHCI have a Transaction
|
||
|
|
Translator built into the root hub.
|
||
|
|
- clocks : a list of phandle + clock specifier pairs
|
||
|
|
- phys : see usb-hcd.txt in the current directory
|
||
|
|
- resets : phandle + reset specifier pair
|
||
|
|
|
||
|
|
additionally the properties from usb-hcd.txt (in the current directory) are
|
||
|
|
supported.
|
||
|
|
|
||
|
|
Example (Sequoia 440EPx):
|
||
|
|
ehci@e0000300 {
|
||
|
|
compatible = "ibm,usb-ehci-440epx", "usb-ehci";
|
||
|
|
interrupt-parent = <&UIC0>;
|
||
|
|
interrupts = <1a 4>;
|
||
|
|
reg = <0 e0000300 90 0 e0000390 70>;
|
||
|
|
big-endian;
|
||
|
|
};
|
||
|
|
|
||
|
|
Example (Allwinner sun4i A10 SoC):
|
||
|
|
ehci0: usb@1c14000 {
|
||
|
|
compatible = "allwinner,sun4i-a10-ehci", "generic-ehci";
|
||
|
|
reg = <0x01c14000 0x100>;
|
||
|
|
interrupts = <39>;
|
||
|
|
clocks = <&ahb_gates 1>;
|
||
|
|
phys = <&usbphy 1>;
|
||
|
|
phy-names = "usb";
|
||
|
|
};
