1USB EHCI controllers 2 3Required properties: 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. 10 11Optional properties: 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 19 - phys : phandle + phy specifier pair 20 - phy-names : "usb" 21 - resets : phandle + reset specifier pair 22 23Example (Sequoia 440EPx): 24 ehci@e0000300 { 25 compatible = "ibm,usb-ehci-440epx", "usb-ehci"; 26 interrupt-parent = <&UIC0>; 27 interrupts = <1a 4>; 28 reg = <0 e0000300 90 0 e0000390 70>; 29 big-endian; 30 }; 31 32Example (Allwinner sun4i A10 SoC): 33 ehci0: usb@01c14000 { 34 compatible = "allwinner,sun4i-a10-ehci", "generic-ehci"; 35 reg = <0x01c14000 0x100>; 36 interrupts = <39>; 37 clocks = <&ahb_gates 1>; 38 phys = <&usbphy 1>; 39 phy-names = "usb"; 40 }; 41
