Please fix your mail client to word wrap within paragraphs at something substantially less than 80 columns. Doing this makes your messages much easier to read and reply to.
In wm8960 codec driver, suspend_bias_off has been enabled. So when system suspend, the wm8960 codec will go to bias off, it will disable VMID and VREF, then sleep 600ms. It seems that 600ms is too long for system suspend.
Because the wm8960 datasheet don't mentioned the sleep time, so i want to check with you if we can shorten the sleep time.
These times are totally normal for a VMID referenced CODEC like the wm8960, attempting to ramp faster produces audible artifacting.
