Broadcom STB USB PHY
Required properties:
- - compatible: brcm,brcmstb-usb-phy
- - reg: two offset and length pairs.
- The first pair specifies a manditory set of memory mapped
- registers used for general control of the PHY.
- The second pair specifies optional registers used by some of
- the SoCs that support USB 3.x
- - #phy-cells: Shall be 1 as it expects one argument for setting
- the type of the PHY. Possible values are:
- - PHY_TYPE_USB2 for USB1.1/2.0 PHY
- - PHY_TYPE_USB3 for USB3.x PHY
+- compatible: should be one of
+ "brcm,brcmstb-usb-phy"
+ "brcm,bcm7216-usb-phy"
+ "brcm,bcm7211-usb-phy"
+
+- reg and reg-names properties requirements are specific to the
+ compatible string.
+ "brcm,brcmstb-usb-phy":
+ - reg: 1 or 2 offset and length pairs. One for the base CTRL registers
+ and an optional pair for systems with USB 3.x support
+ - reg-names: not specified
+ "brcm,bcm7216-usb-phy":
+ - reg: 3 offset and length pairs for CTRL, XHCI_EC and XHCI_GBL
+ registers
+ - reg-names: "ctrl", "xhci_ec", "xhci_gbl"
+ "brcm,bcm7211-usb-phy":
+ - reg: 5 offset and length pairs for CTRL, XHCI_EC, XHCI_GBL,
+ USB_PHY and USB_MDIO registers and an optional pair
+ for the BDC registers
+ - reg-names: "ctrl", "xhci_ec", "xhci_gbl", "usb_phy", "usb_mdio", "bdc_ec"
+
+- #phy-cells: Shall be 1 as it expects one argument for setting
+ the type of the PHY. Possible values are:
+ - PHY_TYPE_USB2 for USB1.1/2.0 PHY
+ - PHY_TYPE_USB3 for USB3.x PHY
Optional Properties:
- clocks : clock phandles.
- clock-names: String, clock name.
+- interrupts: wakeup interrupt
+- interrupt-names: "wakeup"
- brcm,ipp: Boolean, Invert Port Power.
Possible values are: 0 (Don't invert), 1 (Invert)
- brcm,ioc: Boolean, Invert Over Current detection.
Possible values are: 0 (Don't invert), 1 (Invert)
-NOTE: one or both of the following two properties must be set
-- brcm,has-xhci: Boolean indicating the phy has an XHCI phy.
-- brcm,has-eohci: Boolean indicating the phy has an EHCI/OHCI phy.
- dr_mode: String, PHY Device mode.
Possible values are: "host", "peripheral ", "drd" or "typec-pd"
If this property is not defined, the phy will default to "host" mode.
+- brcm,syscon-piarbctl: phandle to syscon for handling config registers
+NOTE: one or both of the following two properties must be set
+- brcm,has-xhci: Boolean indicating the phy has an XHCI phy.
+- brcm,has-eohci: Boolean indicating the phy has an EHCI/OHCI phy.
