Hi Frank,
Now imx8mp-evk switch to support IW612 wifi, which should use "nxp,88w8987-bt" compatible.

Was USB wakeup tested? That beeing said, marking the device as
wakeup-src is fine.

Would be nice to know why the port is needed? If it's just a UART on the
pin header I would rather keep it un-muxed to keep it easy to adapt the
EVK to dev needs.

Hm.. since when does the base.dtsi provide decisions about wakeup
sources. I would rather keep it per board design.

Just noticed that this targets the base soc.dtsi. IMHO this is board
desicion to make and therefore belongs to the real board.dts(i) or dtso.

Therefore please drop my r-b.

wakeup-source is captiblity of hardware. The user need use echo 1 > wakeup

I know that but still if the your system doesn't want to have the usb
exposed as wakeup-source in the first place, the board.dts(i) files are
now forced to delete this property. Therefore IMHO it's still a board
decision to make.
