Enabling wakeup in zynqMp we need to put the core into hibernation, as versal don't have hibernation concept, but we require interrupt for wakeup.
We have a versal platform where we are not using hibernation, but system wake up we need the interrupt. For this interrupt-name enum would be:
- enum [host, peripheral, otg, usb-wakeup]
zynqMp :
- enum [host, peripheral, otg, hiber]
Versal:
- enum [host, peripheral, otg, usb-wakeup]
That's a different name you use now...
It is small confusion.
We have dwc3 in 3 SOCs. ZynqMP/Versal and Versal NET.
In ZynqMP currently we are define it as
interrupt-names = "dwc_usb3", "otg", "hiber";
(https://github.com/Xilinx/u-boot-xlnx/blob/master/arch/arm/dts/zynqmp.dtsi#L996)
where I think we should be able to convert it
host, peripheral, otg, hiber
And Versal (Versal NET is the same as Versal) is now using
interrupt-names = "dwc_usb3","otg","usb-wakeup";
https://github.com/Xilinx/u-boot-xlnx/blob/master/arch/arm/dts/versal.dtsi#L597
where it can be converted to
host, peripheral, otg, usb-wakeup
but the last usb-wakeup entry is the problematic one.
You mentioned before if this is SOC specific maybe we should consider to create
new compatible string to match this.
Thanks,
Michal
