ASoC: SOF: Add dsp_max_burst_size_in_ms member to snd_sof_pcm_stream

Browse source

The dsp_max_burst_size_in_ms can be used to save the length of the maximum
burst size in ms the host DMA will use.

Platform code can place constraint using this to avoid user space
requesting too small ALSA buffer which will result xruns.
