From: Bartosz Golaszewski <bgolaszewski@baylibre.com>

Linus,

this is my second batch of GPIO updates for v5.5.

The most important feature are the new user-space interfaces from Kent
Gibson. Other than that, there are a few minor changes to various
drivers I picked up. More details are in the signed tag.

Please note that this PR has Greg KH's driver-core-next branch merged in
to satisfy the dependencies of the tegra186 patches from Thierry. This
should still cleanly merge with your for-next branch.

Please pull.

The following changes since commit 70d97e099bb426ecb3ad4bf31e88dbf2ef4b2e4c:

  Revert "gpio: expose pull-up/pull-down line flags to userspace" (2019-11-08 13:37:54 +0100)

  gpio: mmio: remove untrue leftover comment (2019-11-13 13:49:42 +0100)

----------------------------------------------------------------
gpio: updates for v5.5

- add MODULE_ALIAS() for bd70528 (makes it possible to autoload the
  module from user-space)
- use proper irc_chip names in gpio-em and gpio-rcar
- expose the line bias settings to user-space in the form of new request
  flags
- expose a new ioctl() to user-space which allows to change certain
  proprties of requested lines without releasing them first
- various updates for gpio-tegra186: debounce support, code
  simplification and interrupt routing
- use platform_get_irq() in gpio-em for some code shrinkage
- remove leftovers after recent gpio-mmio changes

Yeps I saw the discussion with Greg, it gets a bit messy when I
send the pull request to Torvalds so I need to be like
"there is a whole bunch of alien stuff in there" but hey driver
core isn't that much and it's uncontroversial, luckily it wasn't DRM
or something. :D

I pulled it into my "devel" branch.

Yours,
Linus Walleij
