Kernel-4.18.0-80.el8_nvidia,tegra124-xusb

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

• 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:
  • Tegra124: usb2-0, usb2-1, usb2-2, hsic-0, hsic-1, usb3-0, usb3-1
  • Tegra132: usb2-0, usb2-1, usb2-2, hsic-0, hsic-1, usb3-0, usb3-1
  • Tegra210: usb2-0, usb2-1, usb2-2, usb2-3, hsic-0, usb3-0, usb3-1, usb3-2,
