As Simon suggests the DMA thing doesn't buy us much in practice, but if we want to get the lis302dl into mainline with an existing timer-based competing implementation already there the interrupt mode bitbang SPI would. So if we are going to blow out our mailreaders on this, let's do it discussing what moves us forward rather than sideways. - -Andy -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org iEYEARECAAYFAkkgX5gACgkQOjLpvpq7dMpB1ACfYIBOJt77Da11p2ylf77v8l+q S8sAn3WEIWmmGV3ZumxjFgrtjdNo+K+/ =RK40 -----END PGP SIGNATURE-----
