TI Keystone USB PHY
|

|

Required properties:
|
||||
- compatible: should be "ti,keystone-usbphy".
|
||||
- #address-cells, #size-cells : should be '1' if the device has sub-nodes
|
||||
with 'reg' property.
|
||||
- reg : Address and length of the usb phy control register set.
|
||||
|
||||
The main purpose of this PHY driver is to enable the USB PHY reference clock
|
||||
gate on the Keystone SOC for both the USB2 and USB3 PHY. Otherwise it is just
|
||||
an NOP PHY driver. Hence this node is referenced as both the usb2 and usb3
|
||||
phy node in the USB Glue layer driver node.

TI Keystone Soc USB Controller
|
||||
|
||||
DWC3 GLUE
|
||||
|
||||
Required properties:
|
||||
- compatible: should be "ti,keystone-dwc3".
|
||||
- #address-cells, #size-cells : should be '1' if the device has sub-nodes
|
||||
with 'reg' property.
|
||||
- reg : Address and length of the register set for the USB subsystem on
|
||||
the SOC.
|
||||
- interrupts : The irq number of this device that is used to interrupt the
|
||||
MPU.
|
||||
- ranges: allows valid 1:1 translation between child's address space and
|
||||
parent's address space.
|
||||
- clocks: Clock IDs array as required by the controller.
|
||||
- clock-names: names of clocks correseponding to IDs in the clock property.
|
||||
|
||||
Sub-nodes:
|
||||
The dwc3 core should be added as subnode to Keystone DWC3 glue.
|
||||
- dwc3 :
|
||||
The binding details of dwc3 can be found in:
|
||||
Documentation/devicetree/bindings/usb/dwc3.txt
