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:
