- 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 : phandle + phy specifier pair
- - phy-names : "usb"
- - resets : phandle + reset specifier pair
- 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@01c14000 {
- compatible = "allwinner,sun4i-a10-ehci", "generic-ehci";
- reg = <0x01c14000 0x100>;
- interrupts = <39>;
- clocks = <&ahb_gates 1>;
- phys = <&usbphy 1>;
- phy-names = "usb";
- };
