[GIT PULL] gpio: updates for v5.16

Bartosz Golaszewski <brgl@xxxxxxxx> · Mon, 8 Nov 2021 14:24:56 +0100

Linus,

Here are this merge window's updates for the GPIO subsystem. We have a single
new driver, new features in others and some cleanups all over the place.
Nothing really stands out and the PR is relatively small.

There's a single patch for the networking subsystem (Acked by David Miller)
that depends on the GPIO changes and one other for the zynqmp firmware driver
similarly acked by the architecture maintainer - Michal Simek.

Details are in the signed tag.
Please pull.

Best Regards,
Bartosz Golaszewski

  virtio_gpio: drop packed attribute (2021-11-04 16:36:54 +0100)

----------------------------------------------------------------
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
