Hi Felix,
Are these commits meant to fix an error you are seeing, or are you trying to eliminate a warning. This devicetree has been in use for a long time and with many versions of PetaLinux.

Hi,
I'm using these device trees with a custom linux yocto build. Without this power sequencing the wifi won't work (the Wifi chip wont turn on). It works on petalinux, because petalinux includes the devicetree of the first version of the Ultra96 [1]. If you look through that file you will see that the power sequencing happens there, which is why it's not needed in the u96v2 device tree when it's used as an extension of the v1 devicetree.

I think that the devicetree for the Ultra96v2 shouldn't be dependent on the one of the first board. It should work on its own.
