Merge tag 'gpio-updates-for-v5.16' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux
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" * tag 'gpio-updates-for-v5.16' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux: virtio_gpio: drop packed attribute gpio: virtio: Add IRQ support gpio: realtek-otto: fix GPIO line IRQ offset gpio: clean up Kconfig file net: mellanox: mlxbf_gige: Replace non-standard interrupt handling gpio: mlxbf2: Introduce IRQ support gpio: mc33880: Drop if with an always false condition gpio: max730x: Make __max730x_remove() return void gpio: aggregator: Wrap access to gpiochip_fwd.tmp[] gpio: modepin: Add driver support for modepin GPIO controller dt-bindings: gpio: zynqmp: Add binding documentation for modepin firmware: zynqmp: Add MMIO read and write support for PS_MODE pin gpio: tps65218: drop unneeded MODULE_ALIAS gpio: max77620: drop unneeded MODULE_ALIAS gpio: xilinx: simplify getting .driver_data gpio: tegra186: Support multiple interrupts per bank gpio: tegra186: Force one interrupt per bank gpio: uniphier: Use helper functions to get private data from IRQ data gpio: uniphier: Use helper function to get IRQ hardware number dt-bindings: gpio: add gpio-line-names to rockchip,gpio-bank.yaml

+title: ZynqMP Mode Pin GPIO controller
+
+description:
+ PS_MODE is 4-bits boot mode pins sampled on POR deassertion. Mode Pin
+ GPIO controller with configurable from numbers of pins (from 0 to 3 per
+ PS_MODE). Every pin can be configured as input/output.
