NVIDIA Tegra xHCI controller
|
||||
============================
|
||||
|
||||
The Tegra xHCI controller supports both USB2 and USB3 interfaces exposed by
|
||||
the Tegra XUSB pad controller.
|
||||
|
||||
Required properties:
|
||||
--------------------
|
||||
- compatible: Must be:
|
||||
- Tegra124: "nvidia,tegra124-xusb"
|
||||
- Tegra132: "nvidia,tegra132-xusb", "nvidia,tegra124-xusb"
|
||||
- Tegra210: "nvidia,tegra210-xusb"
|
||||
- reg: Must contain the base and length of the xHCI host registers, XUSB FPCI
|
||||
registers and XUSB IPFS registers.
|
||||
- reg-names: Must contain the following entries:
|
||||
- "hcd"
|
||||
- "fpci"
|
||||
- "ipfs"
|
||||
- interrupts: Must contain the xHCI host interrupt and the mailbox interrupt.
|
||||
- clocks: Must contain an entry for each entry in clock-names.
|
||||
See ../clock/clock-bindings.txt for details.
|
||||
- clock-names: Must include the following entries:
|
||||
- xusb_host
|
||||
- xusb_host_src
|
||||
- xusb_falcon_src
|
||||
- xusb_ss
|
||||
- xusb_ss_src
|
||||
- xusb_ss_div2
|
||||
- xusb_hs_src
|
||||
- xusb_fs_src
|
||||
- pll_u_480m
|
||||
- clk_m
|
||||
- pll_e
|
||||
- resets: Must contain an entry for each entry in reset-names.
|
||||
See ../reset/reset.txt for details.
|
||||
- reset-names: Must include the following entries:
|
||||
- xusb_host
|
||||
- xusb_ss
|
||||
- xusb_src
|
||||
Note that xusb_src is the shared reset for xusb_{ss,hs,fs,falcon,host}_src.
|
||||
- nvidia,xusb-padctl: phandle to the XUSB pad controller that is used to
|
||||
configure the USB pads used by the XHCI controller
|
||||
|
||||

|
||||
- avdd-usb-supply: USB controller power supply. Must supply 3.3 V.
|
||||
- avdd-pll-utmip-supply: UTMI PLL power supply. Must supply 1.8 V.
|
||||
- avdd-pll-uerefe-supply: PLLE reference PLL power supply. Must supply 1.05 V.
|
||||
- dvdd-pex-pll-supply: PCIe/USB3 PLL power supply. Must supply 1.05 V.
|
||||
- hvdd-pex-pll-e-supply: High-voltage PLLE power supply. Must supply 1.8 V.
|
||||
|
||||
Optional properties:
|
||||
--------------------
|
||||
- phys: Must contain an entry for each entry in phy-names.
|
||||
See ../phy/phy-bindings.txt for details.
|
||||
- phy-names: Should include an entry for each PHY used by the controller. The
|
||||
following PHYs are available:
