|
|
|
||
|
|
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
|
||
|
|
- phys : see usb-hcd.txt in the current directory
|
||
|
|
- resets : a list of phandle + reset specifier pairs
|
||
|
|
|
||
|
