From the datasheet, the only way to meet the lowest power consumption is to pull low the 'pwdnn' gpio. But if it is low, IC will keep in reset state, all registers reset to default. And the power consumption is listed below 1. amp off and 'pwdnn' high => idle state, PVDD = 1mA, DVDD = 7mA 2. amp off and 'pwdnn' low => shutdown state, PVDD < 20uA, DVDD < 15uA It's the large difference for the consumption current This fix is to use pm_runtime and regcache to handle 'pwdnn' gpio control.
