Subject: wm8960 sleep time is too long when system suspend
Date: Mon, 2 Nov 2015 16:44:04 +0800	[thread overview]
Message-ID: <20151102084402.GA7603@shlinux2> (raw)

Hi Mark,

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.



Best Regards,
Zidan Wang
