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"
