Linux kernel source tree

Currently, we specify the timeout in terms of the number of polls but it is more clear from a user of the functions perspective to specify the timeout directly in milliseconds, as such update the function to these new semantics. Additionally, arizona_poll_reg essentially hard-codes regmap_read_poll_timeout, update the implementation to use regmap_read_poll_timeout. We still keep arizona_poll_reg around as regmap_read_poll_timeout is a macro so rather than expand this for each caller keep it wrapped in arizona_poll_reg. Whilst we are doing this make the timeouts a little more generous as the previous system had a bit more slack as it was done as a delay per iteration of the loop whereas regmap_read_poll_timeout compares ktime's.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
