1 Microchip USB 2.0 Hi-Speed Hub Controller
3 The device node for the configuration of a Microchip USB251xB/xBi USB 2.0
7 - compatible : Should be "microchip,usb251xb" or one of the specific types:
8 "microchip,usb2512b", "microchip,usb2512bi", "microchip,usb2513b",
9 "microchip,usb2513bi", "microchip,usb2514b", "microchip,usb2514bi"
10 - reset-gpios : Should specify the gpio for hub reset
11 - reg : I2C address on the selected bus (default is <0x2C>)
14 - skip-config : Skip Hub configuration, but only send the USB-Attach command
15 - vendor-id : Set USB Vendor ID of the hub (16 bit, default is 0x0424)
16 - product-id : Set USB Product ID of the hub (16 bit, default depends on type)
17 - device-id : Set USB Device ID of the hub (16 bit, default is 0x0bb3)
18 - language-id : Set USB Language ID (16 bit, default is 0x0000)
19 - manufacturer : Set USB Manufacturer string (max 31 characters long)
20 - product : Set USB Product string (max 31 characters long)
21 - serial : Set USB Serial string (max 31 characters long)
22 - {bus,self}-powered : selects between self- and bus-powered operation (default
24 - disable-hi-speed : disable USB Hi-Speed support
25 - {multi,single}-tt : selects between multi- and single-transaction-translator
27 - disable-eop : disable End of Packet generation in full-speed mode
28 - {ganged,individual}-sensing : select over-current sense type in self-powered
29 mode (default is individual)
30 - {ganged,individual}-port-switching : select port power switching mode
31 (default is individual)
32 - dynamic-power-switching : enable auto-switching from self- to bus-powered
33 operation if the local power source is removed or unavailable
34 - oc-delay-us : Delay time (in microseconds) for filtering the over-current
35 sense inputs. Valid values are 100, 4000, 8000 (default) and 16000. If
36 an invalid value is given, the default is used instead.
37 - compound-device : indicate the hub is part of a compound device
38 - port-mapping-mode : enable port mapping mode
39 - string-support : enable string descriptor support (required for manufacturer,
40 product and serial string configuration)
41 - non-removable-ports : Should specify the ports which have a non-removable
43 - sp-disabled-ports : Specifies the ports which will be self-power disabled
44 - bp-disabled-ports : Specifies the ports which will be bus-power disabled
45 - power-on-time-ms : Specifies the time it takes from the time the host
46 initiates the power-on sequence to a port until the port has adequate
47 power. The value is given in ms in a 0 - 510 range (default is 100ms).
