of_gpio.h is deprecated, update the driver to use GPIO descriptors. - Use devm_gpiod_get_optional to get GPIO descriptor. - Use gpiod_set_value to configure output value. With legacy of_gpio API, the driver set GPIO value 1 to power up AK5386, and set value 0 to power down. Per datasheet for PDN(reset_gpio in the driver): Power Down & Reset Mode Pin “H”: Power up, “L”: Power down & Reset The AK5386 must be reset once upon power-up. There is no in-tree DTS using this codec, and the bindings does not specify polarity. Per driver and datasheet, the GPIO polarity should be active-high which is to power up the codec. So using GPIOD_OUT_LOW when get the GPIO descriptor matches GPIOF_OUT_INIT_LOW when using of_gpio API.

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 reStructuredText 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.
