Required properties:
|
||
|
|
- compatible : must be "st,st-ehci-300x"
|
||
|
|
- reg : physical base addresses of the controller and length of memory mapped
|
||
|
|
region
|
||
|
|
- interrupts : one EHCI interrupt should be described here
|
||
|
|
- pinctrl-names : a pinctrl state named "default" must be defined
