Thanks Sascha for your Informations.
The Problem was solved by adding soc-cache.c and changing the KARO-SPI
driver with them from Mainline.
The codec is still running, but now we have another problem.
The AD1938 has 8 channels, the driver for i.mx25 supports 2 channels.
How we can solve the Problem?
static int imx_ad1938_hw_params(struct snd_pcm_substream *substream,
struct snd_pcm_hw_params *params)
{
struct snd_soc_pcm_runtime *rtd = substream->private_data;
struct snd_soc_dai_link *machine = rtd->dai;
struct snd_soc_dai *cpu_dai = machine->cpu_dai;
struct snd_soc_dai *codec_dai = machine->codec_dai;
struct imx_ssi *ssi_mode = cpu_dai->private_data;
unsigned int channels = params_channels(params);
u32 dai_format;
int ret;
ssi_mode->sync_mode = 1;
if (channels == 1)
ssi_mode->network_mode = 0;
else
ssi_mode->network_mode = 1;
dai_format = SND_SOC_DAIFMT_DSP_A |
SND_SOC_DAIFMT_IB_IF | SND_SOC_DAIFMT_CBM_CFM;
/* set codec DAI configuration */
ret = snd_soc_dai_set_fmt(codec_dai, dai_format);
if (ret) {
pr_err("%s: failed set codec dai format\n", __func__);
return ret;
}
/* set codec DAI slots, 8 channels, all channels are enabled */
ret = snd_soc_dai_set_tdm_slot(codec_dai, 0xFF, 0xFF, 8, 32);
if (ret) {
pr_err("%s: failed set codec dai tdm slot\n", __func__);
return ret;
}
