Many portions of the driver need to wait until a given bit is set or cleared. Some busses even have a specific implementation for this operation. In preparation for such variant, implement a generic Wait Bit routine that can be used by the driver core functions. This allows us to get rid of the custom implementations we may find in the driver. Note that for the EEPROM bits, BUSY and RUNNING bits are independent, thus it is more efficient to wait independently for each bit instead of waiting for their mask.

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.
