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
|

|
|
+ - 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.
