Linus Torvalds d20f7a09e5 gpio updates for v5.16
- new driver: gpio-modepin (plus relevant change in zynqmp firmware)
 - add interrupt support to gpio-virtio
 - enable the 'gpio-line-names' property in the DT bindings for gpio-rockchip
 - use the subsystem helpers where applicable in gpio-uniphier instead of
   accessing IRQ structures directly
 - code shrink in gpio-xilinx
 - add interrupt to gpio-mlxbf2 (and include the removal of custom interrupt
   code from the mellanox ethernet driver)
 - support multiple interrupts per bank in gpio-tegra186 (and force one interrupt
   per bank in older models)
 - fix GPIO line IRQ offset calculation in gpio-realtek-otto
 - drop unneeded MODULE_ALIAS expansions in multiple drivers
 - code cleanup in gpio-aggregator
 - minor improvements in gpio-max730x and gpio-mc33880
 - Kconfig cleanups

Pull gpio updates from Bartosz Golaszewski:
 "We have a single new driver, new features in others and some cleanups
  all over the place.

  Nothing really stands out and it is all relatively small.

   - new driver: gpio-modepin (plus relevant change in zynqmp firmware)

   - add interrupt support to gpio-virtio

   - enable the 'gpio-line-names' property in the DT bindings for
     gpio-rockchip

   - use the subsystem helpers where applicable in gpio-uniphier instead
     of accessing IRQ structures directly

   - code shrink in gpio-xilinx

   - add interrupt to gpio-mlxbf2 (and include the removal of custom
     interrupt code from the mellanox ethernet driver)

   - support multiple interrupts per bank in gpio-tegra186 (and force
     one interrupt per bank in older models)

   - fix GPIO line IRQ offset calculation in gpio-realtek-otto

   - drop unneeded MODULE_ALIAS expansions in multiple drivers

   - code cleanup in gpio-aggregator

   - minor improvements in gpio-max730x and gpio-mc33880

   - Kconfig cleanups"

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.
