We are having trouble integrating pcm5121 driver into Qualcomm machine driver apq8009-i2s. We are told that the relevant pcm5121 dai values need to be plugged into this struct, but I haven't been successful.
static struct snd_soc_dai_link apq8009_mi2s_be_dai[] = {
/* Backend DAI Links */
{
.name = LPASS_BE_QUAT_MI2S_TX,
.stream_name = "Quaternary MI2S Capture",
.cpu_dai_name = "msm-dai-q6-mi2s.3",
.platform_name = "msm-pcm-routing",
.codec_name = "snd-soc-dummy",
.codec_dai_name = "snd-soc-dummy-dai",
.no_pcm = 1,
.dpcm_capture = 1,
.be_id = MSM_BACKEND_DAI_QUATERNARY_MI2S_TX,
.be_hw_params_fixup = msm_tx_be_hw_params_fixup,
.ops = &apq8009_quat_mi2s_be_ops,
.ignore_suspend = 1,
},
{
.name = LPASS_BE_PRI_MI2S_RX,
.stream_name = "Primary MI2S Playback",
.cpu_dai_name = "msm-dai-q6-mi2s.0",
.platform_name = "msm-pcm-routing",
.codec_name = "snd-soc-dummy",
.codec_dai_name = "snd-soc-dummy-dai",
.no_pcm = 1,
.dpcm_playback = 1,
.init = &msm_init_mi2s,
.be_id = MSM_BACKEND_DAI_PRI_MI2S_RX,
.be_hw_params_fixup = msm_pri_rx_be_hw_params_fixup,
.ops = &apq8009_mi2s_be_ops,
.ignore_suspend = 1,
},
};
I already have kernel config options enabled for pcm512x driver, and the device tree entry. Any advice would be greatly appreciated.
