Hi Leo,

a couple of minor issues.

commit 7e2173cf82d0bc235b695460c56d46927febdf36 makes PUE to set
automatically PKE. Board files have to set only the required value for
pullup. In your case, you need to put in the mask only
PAD_CTL_PUS_100K_UP, dropping PAD_CTL_PKE | PAD_CTL_PUE.

Ditto.

Is there also a DL version ? If not, you could drop the #ifdef
