This driver may use one of two resets controllers. Keep them in separate variables to keep things simple. The reset controller "rescal" is shared between the AHCI driver and the PCIe driver for the BrcmSTB 7216 chip. Use devm_reset_control_get_optional_shared() to handle this sharing.

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.
