Thanks. That's fine, but that detail should be explained in the
binding. Is there a specific compatible string this can be limited to?
It should also be stated that the GPIO flags should be correct rather
than ignored implying I can put in whatever I want there. Then someday
if no more wrong dtbs are in the wild, it can switch back to using
gpio flags. Also, phy-reset-active-low should be prefixed with "fsl,".
