I'm still getting issues for SPI with this: [ 50.952845] s3c64xx-spi s3c6410-spi.0: Failed to get RX DMA channel [ 50.953520] spi_master spi0: failed to prepare transfer hardware when I test (with -next with this series applied on top), this is from the first transfer that tries to DMA - there's actually no RX data. No errors are reported by the DMA controller itself. I'm also getting crashes setting up the audio DMA while derferencecing the channel. This is without DT - are there any hookups missing because of that? --aVF5wPVC5Z7LhB4n Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.20 (GNU/Linux) iQIcBAEBAgAGBQJSCXGGAAoJELSic+t+oim9XdEP/jjU2+VNZYOHerrBv1kvn4ru 4Y/cKtRQSgnvuhubIWr0eEiHa5gOYz7I27efZlbas90no+x7PkrQ9lHrJyzSXRGm w3rSHitDX3D+m18jam6Rl2Ok4Kaz1NkRhaiR4HXFj7hmsIzqjNBegEpHxTcAOJIp d5hslTMzUB+3uwAoVuIuS2lSyGKeTnT0WXeaB+qjmvamYDx8fU3YNDVX1Lf/3qBg 0aIreTf5HqhyA7XYpaDotUQh4IcbkLJzUKCNyPQtph9H0e6+gvPpmjSPQqWd3VoO 2Cfw9XXuIpDonW9PTflCPIxuOTbh7eEFtuYR0ZGcvhDWrax5dm82txJKy/6JQE/9 pwsSyYZQWIcZ+UU2knj/wAfG4/wJQfOe81D6nANID3loWfpl6jEE9ooLF0Y8FcVw 8+OrcD3RDLo3Xo/1HsHG6sxTYMlthh4HkA9EVjHp+lks8xm+VjSbj+oifoh6XfOI sdUW4c/Qt/etsB/p/VceNcb/cHpmGBaM9S5uMSkSj1jBEGIFdF1yxxk4GGzvDCX7 PFfPFqfEHiBbmanBRTP/tbOwYknVhpCRvwprjUEW9oaakL+AoGXAG7uG2pKZT5/i dCuU4F9Gul4EbiG2HPYXPlOlCdSdWatPlG4YdpfX16J8UBduo07dgnqKhURPxwCg AbKwZ+IOADF6htqXUWtp =Vh+Z -----END PGP SIGNATURE----- --aVF5wPVC5Z7LhB4n-- -- 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/
