If the McBSP is doing anything at all it should still be properly represented with the actual device rather than a dummy otherwise we'll most likely get confused at some point. If it's not doing anything then we shouldn't even need the dummy. But perhaps I'm confused about this particular system, I remember some of the OMAP designs were a bit fun. > But I guess in some cases mcbsp could be the clock-master and then the > secondary DAI would have ops. It'd be a bit of an unusual clock design for a phone but yeah. --jTlsQtO0VwrbBARu Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAl5G/ZAACgkQJNaLcl1U h9CR+Qf9FPZ/Ad8y5xe0+tkWOFeKHsAJS6dhcJcsAkuHoO9VnHgr8uNfN1Pl6LQh W2bWc/5F07FYANvhVtVGyj23F2CnzPyewfjG6BGlToQRLZT3HGc0CPLNrnI4vDgb D+dK9EROqaeuDPppBbdxD0UiURFkB+OGKhIaFjQDhVDlLdr7hBvfPgDdzyilifh9 K5wfAWGUPAjkNRW3IPVAfQZWuCoImOdkVmKTo9cUdxBqB052blAH/Dl6dCAIPXFH 04abRiijYC91F2xNX/XU6XlOWgm2fUCrnmI6K44W71aHyGWPunQd3zhnZpyZXf5K +vKda5XCIvxFmrVHN4BnbN4qz/Xu0Q== =q3Lt -----END PGP SIGNATURE----- --jTlsQtO0VwrbBARu--
