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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
