1HiSilicon STB xHCI
2
3The device node for HiSilicon STB xHCI host controller
4
5Required properties:
6 - compatible: should be "hisilicon,hi3798cv200-xhci"
7 - reg: specifies physical base address and size of the registers
8 - interrupts : interrupt used by the controller
9 - clocks: a list of phandle + clock-specifier pairs, one for each
10	entry in clock-names
11 - clock-names: must contain
12	"bus": for bus clock
13	"utmi": for utmi clock
14	"pipe": for pipe clock
15	"suspend": for suspend clock
16 - resets: a list of phandle and reset specifier pairs as listed in
17	reset-names property.
18 - reset-names: must contain
19	"soft": for soft reset
20 - phys: a list of phandle + phy specifier pairs
21 - phy-names: must contain at least one of following:
22	"inno": for inno phy
23	"combo": for combo phy
24
25Optional properties:
26  - usb2-lpm-disable: indicate if we don't want to enable USB2 HW LPM
27  - usb3-lpm-capable: determines if platform is USB3 LPM capable
28  - imod-interval-ns: default interrupt moderation interval is 40000ns
