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
