Thanks for reply, i am testing all these days, but the problem is
still exists even if using bus reset.

The problem i encountered is that hda_call_codec_resume returned 
timeout of 120 seconds(defined CONFIG_DPM_WATCHDOG)) when doing s4, 
azx_get_response timeout occured, it is a low probability event.

To avoid exceeding 120s, can i change the count value to 3 in 
hda_set_power_state ?
