Hi, I'm almost done with transition to linux-2.6.25, but I can't find a way to convert this snippet from sound/soc/pxa/ezx.c:
static int ezx_machine_prepare(struct snd_pcm_substream *substream)
{
struct snd_soc_pcm_runtime *rtd = substream->private_data;
struct snd_soc_codec_dai *codec_dai = rtd->dai->codec_dai;
struct snd_soc_cpu_dai *cpu_dai = rtd->dai->cpu_dai;
if (codec_dai->id == PCAP2_STEREO_DAI) {
/* override pxa2xx-ssp sample size for stereo/network mode */
SSCR0_P(cpu_dai->id+1) &= ~(SSCR0_DSS | SSCR0_EDSS);
SSCR0_P(cpu_dai->id+1) |= (SSCR0_EDSS | SSCR0_DataSize (16));
}
return 0;
}
SSCR0_P() macro is no longer available.
Philipp Zabel told me that SSCR0 changes should happen only in
pxa2xx-ssp.c but I can't find a way to invoke changes to cpu_dai
hw_params from a machine file.
Does it have any sense to call cpu_dai->ops.hw_params() directly from
ezx_machine_prepare? I expect this call to invoke pxa2xx_ssp_hw_params
in our case, which should do the initialization we want if it finds
SNDRV_PCM_FORMAT_S32_LE in the params argument. But how to setup the
params argument?
Thanks,
Antonio
