SND_SOC_DAIFMT_xxx comment indicates "codec clk/FRM" indeed. but does this "codec" means "codec chip" ?? I'm not sure. but anyway, if my understanding is correct, simple-audio-card,cpu { ... bitclock-master; frame-master; }; simple-audio-card,codec { ... bitclock-master; frame-master; }; This will be cpu : SND_SOC_DAIFMT_CBS_CFS codec : SND_SOC_DAIFMT_CBM_CFM but, it is un-understandable/confusable for me, and it breaks our sound card. ${LINUX}/arch/arm/boot/dts/sh73a0-kzm9g-reference.dts ${LINUX}/arch/arm/boot/dts/r8a7740-armadillo800eva-reference.dts I guess you want like this ? codec-bitclock-master; codec-frame-master; simple-audio-card,cpu { ... }; simple-audio-card,codec { ... }; # And I guess [1/2] and [2/2] should be 1 patch. # otherwise, it breaks git-bisect :P Best regards --- Kuninori Morimoto -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
