There's a bunch of other drivers using the SYSCLK thing, when you call set_sysclk() they provide a different SYSCLK number if they want to use manual mode. If there's a concern about drivers doing stuff on init you could always ask them to set the PLL during init, even if only briefly. --GvXjxJ+pjyke8COw Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAl3ebQoACgkQJNaLcl1U h9BDaQf/ZAlgmS17icedamvRKebKOojZ+VtpiJMgMsOiLs1eMu10rJm/6XiCT5sh dvPRA9mGno4nal5L/s8UHj3CFPkHSYqPGI/uwY4Gf4Ek2B9cyMHiW3ht1MozjcDH I2QMxZxMhqHCf1p5a8fh+2jlyFfwC8lpluRg57rLT5PTdb27MBbrshYHlPuuxKtk p7U1irpsbnO6iW3CAp9N8kIc996SItJ7230JQCHXdLJ0X773ekOLQTSb5Ypn0Y/f kD+NRNoggRWJ70XZqm3DwMQRdGIW33IWR/nS+W0ncP93hfneMjYpp4byZ+BGWOwy CozlfXK15fWw/kq+9Gw1LGWv9CKSxw== =thrJ -----END PGP SIGNATURE----- --GvXjxJ+pjyke8COw-- --===============5152261682617373311== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ Alsa-devel mailing list Alsa-devel@alsa-project.org https://mailman.alsa-project.org/mailman/listinfo/alsa-devel --===============5152261682617373311==--
