i.MX8MQ/MN/MM/MP platforms typically have 2 AUDIO PLLs being configured to handle 8kHz and 11kHz series audio rates. Add common function in fsl_utils to handle these two PLL clock source, which are needed by CPU DAI drivers Signed-off-by: Shengjiu Wang <shengjiu.wang@nxp.com> Link: https://lore.kernel.org/r/1656667961-1799-2-git-send-email-shengjiu.wang@nxp.com Signed-off-by: Mark Brown <broonie@kernel.org>
