This converts the DS2404 to use GPIO descriptors instead of hard-coded global GPIO numbers. The platform data can be deleted because there are no in-tree users and it only contained GPIO numbers which are now passed using descriptor tables (or device tree or ACPI). The driver was rewritten to use a state container for the device driver state (struct ds2404 *chip) and pass that around instead of using a global singleton storage for the GPIO handles. When declaring GPIO descriptor tables or other hardware descriptions for the RTC driver, implementers should take care to flag the RESET line as active low, such as by using the GPIOD_ACTIVE_LOW flag in the descriptor table.

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.
