A fallback compatible, since you;re using the same match data as the 8041. > It's similar in that the USB8044 provides the same functionality and can = use > the same driver as the USB8041, all that is needed is to add the PID/VID > values. Is this onboard_dev_id_table table with the vid/pid used in combination with dt, or in-place of dt when device detection is dynamic? If the latter, why can't dt use a fallback compatible since the handling is identical to the 8041? --CzRFXEYtV/KODyA2 Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iHUEABYIAB0WIQRh246EGq/8RLhDjO14tDGHoIJi0gUCaBzTdwAKCRB4tDGHoIJi 0husAQDKJqY0447aERdg222zT8s/YoH4aP4Fr0oCykX3UpOeigD+PG/530cegue/ c/rAjQgKDz02F8mUNaWT2IxzwE2doAc= =bHDE -----END PGP SIGNATURE----- --CzRFXEYtV/KODyA2--
