1 SMSC USB3503 High-Speed Hub Controller
4 - compatible: Should be "smsc,usb3503" or "smsc,usb3503a".
7 - reg: Specifies the i2c slave address, it is required and should be 0x08
9 - connect-gpios: Should specify GPIO for connect.
10 - disabled-ports: Should specify the ports unused.
11 '1' or '2' or '3' are available for this property to describe the port
12 number. 1~3 property values are possible to be described.
13 Do not describe this property if all ports have to be enabled.
14 - intn-gpios: Should specify GPIO for interrupt.
15 - reset-gpios: Should specify GPIO for reset.
16 - initial-mode: Should specify initial mode.
17 (1 for HUB mode, 2 for STANDBY mode)
18 - refclk: Clock used for driving REFCLK signal (optional, if not provided
19 the driver assumes that clock signal is always available, its
20 rate is specified by REF_SEL pins and a value from the primary
21 reference clock frequencies table is used)
22 - refclk-frequency: Frequency of the REFCLK signal as defined by REF_SEL
23 pins (optional, if not provided, driver will not set rate of the
24 REFCLK signal and assume that a value from the primary reference
25 clock frequencies table is used)
