I appreciate that is > more work but it is likely a nicer solution overall. GPIO chips are small and simple enough that we've not worried about it historically. However my question here is why this is wm9713 specific - the GPIO functionality is part of the AC'97 spec and present on many AC'97 chips so it seems sensible to have something at the AC'97 level. Unfortunately a quick check seems not to show anything indicating this in the AC'97 capability information so we might want to make it opt in. --s8J8qjRpxLkp1Gun Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQEcBAEBCAAGBQJWOy7uAAoJECTWi3JdVIfQIpEH/1fq3vyS2WZ8Dt+sdu2PECxV J8S9/6sxGCaBNz125tQcngKmPc1VxqMVagaDys5aZHykmyVQbs1qM6DVQFvtf5LD zX/m8gwxJWu/OE6FivKgj4GLJZzcUwZvRSYwVjz9vb8iONUyR0dN2vp1uEIz2gD+ vzU4FjdFkuvDf8WW0sXDV0Tzfnvd4U9Mese0qKYVf2ZaYt3dGD701FYFxNYLz1C8 6+w9UZUu8RNaf3A2ZYf3dBBpnTDBYyCNMZvT5J01pgPz/lejipUKKcekATRoB6ki +GDUoKu2+Hv2Tpco0H2X15Q6doSrjaktztUT1/vBupmf2x1O88gxnA3rGAGbvIM= =QWx0 -----END PGP SIGNATURE----- --s8J8qjRpxLkp1Gun-- -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
