How does the Linux kernel deal with that?
I don't see such property in the mainline kernel or in the NXP tree.
I am concerned that we add a U-Boot specific here. Also, the fact that common code waits 10ms is a driver implementation detail, so not happy that such information needs to be passed in the U-Boot dts.
