Merge tag 'gpio-updates-for-v5.12' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux 

Pull gpio updates from Bartosz Golaszewski:
 "It's been a relatively calm release cycle and we're actually removing
  more code than we're adding.

  Summary:

   - new driver for the Toshiba Visconti platform

   - rework of interrupt handling in gpio-tegra

   - updates for GPIO selftests: we're now using the character device to
     perform the subsystem checks

   - support for a new rcar variant + some code refactoring

   - refactoring of gpio-ep93xx

   - SPDX License identifier has been updated in the uapi header so that
     userspace programs bundling it can become fully REUSE-compliant

   - improvements to pwm handling in gpio-mvebu

   - support for interrupt handling and power management for gpio-xilinx
     as well as some code refactoring

   - support for a new chip variant in gpio-pca953x

   - removal of drivers: zte xs & intel-mid and removal of leftovers
     from intel-msic

   - impovements to intel drivers pulled from Andy Shevchenko

   - improvements to the gpio-aggregator virtual GPIO driver

   - and several minor tweaks and fixes to code and documentation all
     over the place"
