The format is:

#define FMT_SSI (SND_SOC_DAIFMT_DSP_A | SND_SOC_DAIFMT_NB_NF | \
		SND_SOC_DAIFMT_CBM_CFM)

In wm1133-ev1.c you did:

	/* TODO: The SSI driver should figure this out for us */
	switch (channels) {
	case 2:
		snd_soc_dai_set_tdm_slot(cpu_dai, 0xffffffc, 0xffffffc, 2, 0);
		break;
	case 1:
		snd_soc_dai_set_tdm_slot(cpu_dai, 0xffffffe, 0xffffffe, 1, 0);
		break;
	default:
		return -EINVAL;
	}

Maybe I should do something similar in imx-mc13783?
