1 Broadcom STB USB PHY
2
3 Required properties:
4 - compatible: should be one of
5 "brcm,brcmstb-usb-phy"
6 "brcm,bcm7216-usb-phy"
7 "brcm,bcm7211-usb-phy"
8
9 - reg and reg-names properties requirements are specific to the
10 compatible string.
11 "brcm,brcmstb-usb-phy":
12 - reg: 1 or 2 offset and length pairs. One for the base CTRL registers
13 and an optional pair for systems with USB 3.x support
14 - reg-names: not specified
15 "brcm,bcm7216-usb-phy":
16 - reg: 3 offset and length pairs for CTRL, XHCI_EC and XHCI_GBL
17 registers
18 - reg-names: "ctrl", "xhci_ec", "xhci_gbl"
19 "brcm,bcm7211-usb-phy":
20 - reg: 5 offset and length pairs for CTRL, XHCI_EC, XHCI_GBL,
21 USB_PHY and USB_MDIO registers and an optional pair
22 for the BDC registers
23 - reg-names: "ctrl", "xhci_ec", "xhci_gbl", "usb_phy", "usb_mdio", "bdc_ec"
24
25 - #phy-cells: Shall be 1 as it expects one argument for setting
26 the type of the PHY. Possible values are:
27 - PHY_TYPE_USB2 for USB1.1/2.0 PHY
28 - PHY_TYPE_USB3 for USB3.x PHY
29
30 Optional Properties:
31 - clocks : clock phandles.
32 - clock-names: String, clock name.
33 - interrupts: wakeup interrupt
34 - interrupt-names: "wakeup"
35 - brcm,ipp: Boolean, Invert Port Power.
36 Possible values are: 0 (Don't invert), 1 (Invert)
37 - brcm,ioc: Boolean, Invert Over Current detection.
38 Possible values are: 0 (Don't invert), 1 (Invert)
39 - dr_mode: String, PHY Device mode.
40 Possible values are: "host", "peripheral ", "drd" or "typec-pd"
41 If this property is not defined, the phy will default to "host" mode.
42 - brcm,syscon-piarbctl: phandle to syscon for handling config registers
43 NOTE: one or both of the following two properties must be set
44 - brcm,has-xhci: Boolean indicating the phy has an XHCI phy.
45 - brcm,has-eohci: Boolean indicating the phy has an EHCI/OHCI phy.
