We should not read sst hw_ptr and pcm_delay in sst_platform_pcm_pointer Since it will be ricky if sst_platform_pcm_pointer is called while dsp is updating the timestamp.Now read sst hw_ptr after period elapse interrupt occurs.
So I guess there's still some risk that we could run into problems here if we take too long to service the interrupt and/or the period is very short? Is there anything we can do to improve that?
