fbdev: sh_mobile_hdmi: modify snd_soc_dai_driver settings
This patch solve below report from Guennadi > +static struct snd_soc_dai_driver sh_hdmi_dai = { > + .name = "sh_mobile_hdmi-hifi", > + .playback = { > + .stream_name = "Playback", > + .channels_min = 1, Can it actually do mono? Maybe at probe time you could look at audio flags from your previous patch and, e.g., for SPDIF set channels_min to 2? > + .channels_max = 2, That's the "smallest max," yes. With some other interfaces (I2S, DSD) it can support up to 8 channels... > + .rates = SNDRV_PCM_RATE_8000_48000, Hm, in the datasheet I see supported frequencies 32kHz to 192kHz. And if you promise support for multiple frequencies, don't you want to implement .hw_params? Besides, not all of these frequencies will be available, depending on your supplied clock and your willingness to implement downsampling.
