-MSM SoC HSUSB controllers
-
-EHCI
-
-Required properties:
-- compatible: Should contain "qcom,ehci-host"
-- regs: offset and length of the register set in the memory map
-- usb-phy: phandle for the PHY device
-
-Example EHCI controller device node:
-
- ehci: ehci@f9a55000 {
- compatible = "qcom,ehci-host";
- reg = <0xf9a55000 0x400>;
- usb-phy = <&usb_otg>;
- };
-
-USB PHY with optional OTG:
-
-Required properties:
-- compatible: Should contain:
- "qcom,usb-otg-ci" for chipsets with ChipIdea 45nm PHY
- "qcom,usb-otg-snps" for chipsets with Synopsys 28nm PHY
-
-- regs: Offset and length of the register set in the memory map
-- interrupts: interrupt-specifier for the OTG interrupt.
-
-- clocks: A list of phandle + clock-specifier pairs for the
- clocks listed in clock-names
-- clock-names: Should contain the following:
- "phy" USB PHY reference clock
- "core" Protocol engine clock
- "iface" Interface bus clock
- "alt_core" Protocol engine clock for targets with asynchronous
- reset methodology. (optional)
-
-- vdccx-supply: phandle to the regulator for the vdd supply for
- digital circuit operation.
-- v1p8-supply: phandle to the regulator for the 1.8V supply
-- v3p3-supply: phandle to the regulator for the 3.3V supply
-
-- resets: A list of phandle + reset-specifier pairs for the
- resets listed in reset-names
-- reset-names: Should contain the following:
- "phy" USB PHY controller reset
- "link" USB LINK controller reset
-
-- qcom,otg-control: OTG control (VBUS and ID notifications) can be one of
- 1 - PHY control
- 2 - PMIC control
-
-Optional properties:
-- dr_mode: One of "host", "peripheral" or "otg". Defaults to "otg"
-
-- switch-gpio: A phandle + gpio-specifier pair. Some boards are using Dual
- SPDT USB Switch, witch is controlled by GPIO to de/multiplex
- D+/D- USB lines between connectors.
-
-- qcom,phy-init-sequence: PHY configuration sequence values. This is related to Device
- Mode Eye Diagram test. Start address at which these values will be
- written is ULPI_EXT_VENDOR_SPECIFIC. Value of -1 is reserved as
- "do not overwrite default value at this address".
- For example: qcom,phy-init-sequence = < -1 0x63 >;
- Will update only value at address ULPI_EXT_VENDOR_SPECIFIC + 1.
-
-- qcom,phy-num: Select number of pyco-phy to use, can be one of
- 0 - PHY one, default
- 1 - Second PHY
- Some platforms may have configuration to allow USB
- controller work with any of the two HSPHYs present.
-
-- qcom,vdd-levels: This property must be a list of three integer values
- (no, min, max) where each value represents either a voltage
- in microvolts or a value corresponding to voltage corner.
-
-- qcom,manual-pullup: If present, vbus is not routed to USB controller/phy
- and controller driver therefore enables pull-up explicitly
- before starting controller using usbcmd run/stop bit.
-
-- extcon: phandles to external connector devices. First phandle
- should point to external connector, which provide "USB"
- cable events, the second should point to external connector
- device, which provide "USB-HOST" cable events. If one of
- the external connector devices is not required empty <0>
- phandle should be specified.
-
