SMSC USB3503 High-Speed Hub Controller
|
|
|
|
Required properties:
|
|
- compatible: Should be "smsc,usb3503" or "smsc,usb3503a".
|
|
|
|
Optional properties:
|
|
- reg: Specifies the i2c slave address, it is required and should be 0x08
|
|
if I2C is used.
|
|
- connect-gpios: Should specify GPIO for connect.
|
|
- disabled-ports: Should specify the ports unused.
|
|
'1' or '2' or '3' are available for this property to describe the port
|
|
number. 1~3 property values are possible to be described.
|
|
Do not describe this property if all ports have to be enabled.
|
|
- intn-gpios: Should specify GPIO for interrupt.
|
|
- reset-gpios: Should specify GPIO for reset.
|
|
- initial-mode: Should specify initial mode.
|
|
(1 for HUB mode, 2 for STANDBY mode)
|
|
- refclk: Clock used for driving REFCLK signal (optional, if not provided
|
|
the driver assumes that clock signal is always available, its
|
|
rate is specified by REF_SEL pins and a value from the primary
|
|
reference clock frequencies table is used)
|
|
- refclk-frequency: Frequency of the REFCLK signal as defined by REF_SEL
|
|
pins (optional, if not provided, driver will not set rate of the
|
|
REFCLK signal and assume that a value from the primary reference
|
|
clock frequencies table is used)
|
|
|
|
Examples:

|
usb3503@08 {
