USB OHCI controllers
|
|
|
|
Required properties:
|
|
- compatible : "generic-ohci"
|
|
- reg : ohci controller register range (address and length)
|
|
- interrupts : ohci controller interrupt
|
|
|
|
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
|
|
- no-big-frame-no : boolean, set if frame_no lives in bits [15:0] of HCCA
|
|
- remote-wakeup-connected: remote wakeup is wired on the platform
|
|
- num-ports : u32, to override the detected port count
|
|
- clocks : a list of phandle + clock specifier pairs. In case of Renesas
|
|
R-Car Gen3 SoCs:
|
|
- if a host only channel: first clock should be host.
|
|
- if a USB DRD channel: first clock should be host and second one
|
|
should be peripheral.
|
|
- phys : see usb-hcd.txt in the current directory
|
|
- resets : a list of phandle + reset specifier pairs
|
|
|
|
additionally the properties from usb-hcd.txt (in the current directory) are
|
|
supported.
|
|
|
|
Example:
|
|
|
|
ohci0: usb@1c14400 {
|
|
compatible = "allwinner,sun4i-a10-ohci", "generic-ohci";
|
|
reg = <0x01c14400 0x100>;
|
|
interrupts = <64>;
|
|
clocks = <&usb_clk 6>, <&ahb_gates 2>;
|
|
phys = <&usbphy 1>;
|
|
phy-names = "usb";
|
|
};
