29 * NOTE: terminology here is confusing.
30 *
31 * - This driver supports the "Audio Serial Port" (ASP),
32 * found on dm6446, dm355, and other DaVinci chips.
33 *
34 * - But it labels it a "Multi-channel Buffered Serial Port"
35 * (McBSP) as on older chips like the dm642 ... which was
36 * backward-compatible, possibly explaining that confusion.
37 *
38 * - OMAP chips have a controller called McBSP, which is
39 * incompatible with the DaVinci flavor of McBSP.
40 *
41 * - Newer DaVinci chips have a controller called McASP,
42 * incompatible with ASP and with either McBSP.
43 *
44 * In short: this uses ASP to implement I2S, not McBSP.
45 * And it won't be the only DaVinci implemention of I2S.
