-Tegra SOC USB PHY
-
-The device node for Tegra SOC USB PHY:
-
-Required properties :
- - compatible : For Tegra20, must contain "nvidia,tegra20-usb-phy".
- For Tegra30, must contain "nvidia,tegra30-usb-phy". Otherwise, must contain
- "nvidia,<chip>-usb-phy" plus at least one of the above, where <chip> is
- tegra114, tegra124, tegra132, or tegra210.
- - reg : Defines the following set of registers, in the order listed:
- - The PHY's own register set.
- Always present.
- - The register set of the PHY containing the UTMI pad control registers.
- Present if-and-only-if phy_type == utmi.
- - phy_type : Should be one of "utmi", "ulpi" or "hsic".
- - clocks : Defines the clocks listed in the clock-names property.
- - clock-names : The following clock names must be present:
- - reg: The clock needed to access the PHY's own registers. This is the
- associated EHCI controller's clock. Always present.
- - pll_u: PLL_U. Always present.
- - timer: The timeout clock (clk_m). Present if phy_type == utmi.
- - utmi-pads: The clock needed to access the UTMI pad control registers.
- Present if phy_type == utmi.
- - ulpi-link: The clock Tegra provides to the ULPI PHY (usually pad DAP_MCLK2
- with pad group aka "nvidia,pins" cdev2 and pin mux option config aka
- "nvidia,function" pllp_out4).
- Present if phy_type == ulpi, and ULPI link mode is in use.
- - resets : Must contain an entry for each entry in reset-names.
- See ../reset/reset.txt for details.
- - reset-names : Must include the following entries:
- - usb: The PHY's own reset signal.
- - utmi-pads: The reset of the PHY containing the chip-wide UTMI pad control
- registers. Required even if phy_type == ulpi.
-
-Required properties for phy_type == ulpi:
- - nvidia,phy-reset-gpio : The GPIO used to reset the PHY.
-
-Required PHY timing params for utmi phy, for all chips:
- - nvidia,hssync-start-delay : Number of 480 Mhz clock cycles to wait before
- start of sync launches RxActive
- - nvidia,elastic-limit : Variable FIFO Depth of elastic input store
- - nvidia,idle-wait-delay : Number of 480 Mhz clock cycles of idle to wait
- before declare IDLE.
- - nvidia,term-range-adj : Range adjusment on terminations
- - Either one of the following for HS driver output control:
- - nvidia,xcvr-setup : integer, uses the provided value.
- - nvidia,xcvr-setup-use-fuses : boolean, indicates that the value is read
- from the on-chip fuses
- If both are provided, nvidia,xcvr-setup-use-fuses takes precedence.
- - nvidia,xcvr-lsfslew : LS falling slew rate control.
- - nvidia,xcvr-lsrslew : LS rising slew rate control.
-
-Required PHY timing params for utmi phy, only on Tegra30 and above:
- - nvidia,xcvr-hsslew : HS slew rate control.
- - nvidia,hssquelch-level : HS squelch detector level.
- - nvidia,hsdiscon-level : HS disconnect detector level.
-
-Optional properties:
- - nvidia,has-legacy-mode : boolean indicates whether this controller can
- operate in legacy mode (as APX 2500 / 2600). In legacy mode some
- registers are accessed through the APB_MISC base address instead of
- the USB controller.
- - nvidia,is-wired : boolean. Indicates whether we can do certain kind of power
- optimizations for the devices that are always connected. e.g. modem.
- - dr_mode : dual role mode. Indicates the working mode for the PHY. Can be
- "host", "peripheral", or "otg". Defaults to "host" if not defined.
- host means this is a host controller
- peripheral means it is device controller
- otg means it can operate as either ("on the go")
- - nvidia,has-utmi-pad-registers : boolean indicates whether this controller
- contains the UTMI pad control registers common to all USB controllers.
-
-VBUS control (required for dr_mode == otg, optional for dr_mode == host):
- - vbus-supply: regulator for VBUS

-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)
