Kernel-4.18.0-80.el8_hisilicon,histb-xhci

HiSilicon STB xHCI

The device node for HiSilicon STB xHCI host controller

Required properties:

  • compatible: should be “hisilicon,hi3798cv200-xhci”
  • reg: specifies physical base address and size of the registers
  • interrupts : interrupt used by the controller
  • clocks: a list of phandle + clock-specifier pairs, one for each
    entry in clock-names
  • clock-names: must contain
    “bus”: for bus clock
    “utmi”: for utmi clock
    “pipe”: for pipe clock
    “suspend”: for suspend clock
  • resets: a list of phandle and reset specifier pairs as listed in
    reset-names property.
  • reset-names: must contain
    “soft”: for soft reset
  • phys: a list of phandle + phy specifier pairs
  • phy-names: must contain at least one of following:
    “inno”: for inno phy
    “combo”: for combo phy

Optional properties:

  • usb2-lpm-disable: indicate if we don’t want to enable USB2 HW LPM
  • usb3-lpm-capable: determines if platform is USB3 LPM capable
  • imod-interval-ns: default interrupt moderation interval is 40000ns

Example:

xhci0: xchi@f98a0000 {
compatible = “hisilicon,hi3798cv200-xhci”;
reg = <0xf98a0000 0x10000>;

<&crg HISTB_USB3_UTMI_CLK>,
<&crg HISTB_USB3_PIPE_CLK>,
<&crg HISTB_USB3_SUSPEND_CLK>;
clock-names = “bus”, “utmi”, “pipe”, “suspend”;
resets = <&crg 0xb0 12>;
reset-names = “soft”;
phys = <&usb2_phy1_port1 0>, <&combphy0 PHY_TYPE_USB3>;
phy-names = “inno”, “combo”;
