In the tda998x driver, the CTS_N is automatic (AIP_CNTRL_0_ACR_MAN is not set). Then, in my Cubox (Marvell A510 + tda19988), the 16, 24 and 32 bits formats are working well with I2S input at any rate. -- Ken ar c'hentañ | ** Breizh ha Linux atav! ** Jef | http://moinejf.free.fr/ -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
