After several quiet kernel releases we've got a couple of new features in regmap, support for using hwspinlocks as the lock for the internal data structures and a helper for polling on regmap_fields. The Kconfig dependencies on hwspinlocks were annoyingly difficult to squash between things behaving surprisingly and randconfig, I could've squashed those commits down but might've have caused hassle with other trees trying to use the new support. - Support for using a hwspinlock to protect the regmap. - An iopoll style helper for regmap_field. -----BEGIN PGP SIGNATURE----- iQFHBAABCgAxFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAloJkKUTHGJyb29uaWVA a2VybmVsLm9yZwAKCRAk1otyXVSH0Nr7B/9XaAdcoGg1FbcNeKrQN88VqGX8pU4W hcVMP4XdMxuBPmp/Rbkdkogvl8//MBGzn7jWnZBU59xkLnB0PfNB/JB5VdOrqT6w k+TdPNbs7s7cxTYubRBguhhEmC85gu2hiNCl+zlurPNBqHIhXXSVq+dNqlw4g4zI 0cm0bTxSCLOppoBPXQXFxa4fAXopNPWeAF7Cg8+oMl6er8p7iILkxFK31JuafKjZ 95RU0ikdmPHhV3OXrcE914hXnhFBM2VQ56z9BI84pwNONdRwWd10wRkoQ7zj4WDN qvNFY8mU/Bg6rHLI4Z2Ksj3zkLQs7VKBgdUL2dGPC/l3WElfFtF0sVkk =FBMj -----END PGP SIGNATURE----- Merge tag 'regmap-v4.15' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap Pull regmap updates from Mark Brown: "After several quiet kernel releases we've got a couple of new features in regmap, support for using hwspinlocks as the lock for the internal data structures and a helper for polling on regmap_fields.

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.
