Hi,
Can you help with setup of mcasp6 in linux.
I'm using the am5728 evm board running the ti-processor-sdk-linux-am57xx-evm-06.02.00.81 linux.
I used the Ti Pinmux tool to setup the u-boot mux_data.h file:
const struct pad_conf_entry core_padconf_array_essential_x15[] = {

I'm using pins A11,A12,B12,B13 for the i2s interface.
I setup my devicetree file as follows:
pcm5102a: pcm5102a {
#sound-dai-cells = <0>;
compatible = "ti,pcm5102a";
status="okay";
};
sound2: sound@2 {
compatible = "simple-audio-card";
simple-audio-card,name = "PCM5102a";
simple-audio-card,format = "i2s";
simple-audio-card,bitclock-master = <&sound2_master>;
simple-audio-card,frame-master = <&sound2_master>;
simple-audio-card,bitclock-inversion;
sound2_master: simple-audio-card,cpu {
sound-dai = <&mcasp6>;
};
simple-audio-card,codec {
#sound-dai-cells = <0>;
sound-dai = <&pcm5102a>;
};
};
&mcasp6 {
#sound-dai-cells = <0>;
status = "okay";
op-mode = <0>; /* MCASP_IIS_MODE */
tdm-slots = <2>;
/* 4 serializers */
serial-dir = < /* 0: INACTIVE, 1: TX, 2: RX */
1 2 0 0
>;
tx-num-evt = <32>;
rx-num-evt = <32>;
};
I also have the codec pcm5102a.c setup as follows:
static struct snd_soc_dai_driver pcm5102a_dai = {
.name = "pcm5102a-hifi",
.playback = {
.channels_min = 2,
.channels_max = 2,
.rates = SNDRV_PCM_RATE_8000_192000,
.formats = SNDRV_PCM_FMTBIT_S8 |
SNDRV_PCM_FMTBIT_S16_LE |
SNDRV_PCM_FMTBIT_S24_LE |
SNDRV_PCM_FMTBIT_S32_LE
},
.capture = {
.stream_name= "Capture",
.channels_min= 1,
.channels_max= 2,
.rates= SNDRV_PCM_RATE_8000_192000,
.formats= SNDRV_PCM_FMTBIT_S16_LE|
SNDRV_PCM_FMTBIT_S24_LE|
SNDRV_PCM_FMTBIT_S32_LE
},
};
The device shows up in linux, but only has one supported format at 8bits. How can I support other bit widths and rates?

I also confirmed that I am getting output on the pins:
Any ideas what is wrong?
