cycle. Core changes: - We have killed off VLA from the core library and all drivers. The background should be clear for everyone at this point: https://lwn.net/Articles/749064/ Also I just don't like VLA's, kernel developers hate it when compilers do things behind their back. It's as simple as that. I'm sorry that they even slipped in to begin with. Kudos to Laura Abbott for exorcising them. - Support GPIO hogs in machines/board files. New drivers and chip support: - R-Car r8a77470 (RZ/G1C) - R-Car r8a77965 (M3-N) - R-Car r8a77990 (E3) - PCA953x driver improvements to accomodate more variants. Improvements and new features: - Support one interrupt per line on port A in the DesignWare dwapb driver. Misc: - Random cleanups, right header files in the drivers, some size optimizations etc. -----BEGIN PGP SIGNATURE----- iQIcBAABAgAGBQJbGOMeAAoJEEEQszewGV1zGR0P/Rq/Mh6BRum7kZee8v22aKJE imtSamaVk7eOSdLC00VLvJ5QYJBMWz2GV5ZJkaxAwHBh1GhfddTDj35uXoOkRRWs vRXSYthujluGJ5YYfRNrXZhD4ahVYPnJV5XxLy4OF+aQBAd4jjRAqXLhQT1PVK9Q AQD/BOjToxrjgPREaLX9sQTW8DbICmjRhEWieJoQab2mZC+qD/aCen0rkj+UD0Qu wQRk5mSEsrC0qmWNS/rhzFa7/nRa4qWOMkHxim7/GqwGzgOTpv+TctmQOqMUjHqq k0ikVgBfZbaz3MqcuqLbKJ00mRK6G/yQIlECP4xcMbxKRxXucJj1ytOedIdG4nJE 5porXbW1d1bIhv3Zv8tt7vh00x+mEF+hv6p8DUa9ppe7qwsdbhUdzeczeyR8eM7U ZBi80jMJfp9wEugZ0F8syIUs3PPgp7y461hJDbZRuHp4P4jmpdUBMAF4XvWl6XPy DAlPHnSc2ZNaqWJtfc1ja4e6DlwltEV81Sd9Y0clLhkD95k95gZ7EzoyGPAIO4FG ir0getZE1mfh9K/EfkTOkcKHJh3b5rA5TiSbTVVaPO9SzqPtIK+xhDJI0r9IJkW1 XKgScOaJqpYEe2Y/Y/ezfnjxDLVxwOz6R77GsZCle1uPevOcxqN9fmjEn7gGYzmX PDf5pOuRrWApqix4a3Jr =Ly/0 -----END PGP SIGNATURE----- Merge tag 'gpio-v4.18-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio Pull GPIO updates from Linus Walleij: "This is the bulk of GPIO changes for the v4.18 development cycle.

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.
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.
