-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). Use clocks and
- clock-names in order to assign it
-- 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@8 {
- compatible = "smsc,usb3503";
- reg = <0x08>;
- connect-gpios = <&gpx3 0 1>;
- disabled-ports = <2 3>;
- intn-gpios = <&gpx3 4 1>;
- reset-gpios = <&gpx3 5 1>;
- initial-mode = <1>;
- clocks = <&clks 80>;
- clock-names = "refclk";
- };
