Hi Linus,

here is the bulk of the GPIO changes for v5.6.
This is a pretty calm cycle so far, nothing special going
on really. Some more changes will come in from the
irqchip and pin control trees.

I also delete an orphan include file for FMC that was
dangling since I deleted that subsystem through the
GPIO tree it comes here again.

Please pull it in!

Yours,
Linus Walleij

The following changes since commit b3a987b0264d3ddbb24293ebff10eddfc472f653:

  Merge tag 'gpio-updates-for-v5.6-part2' of
git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux into devel
(2020-01-26 01:01:55 +0100)

----------------------------------------------------------------
This is the bulk of GPIO changes for the v5.6 kernel cycle

Core changes:

- Document the usecases for the kernelspace vs userspace
  handling of GPIOs.

- Handle MSI (message signalled interrupts) properly in the
  core hierarchical irqdomain code.

- Fix a rare race condition while initializing the descriptor
  array.

New drivers:

- Xylon LogiCVC GPIO driver.

- WDC934x GPIO controller driver.

Driver improvements:

- Implemented suspend/resume in the Tegra driver.

- MPC8xx edge detection fixup.

- Properly convert ThunderX to use hierarchical irqdomain
  with GPIOLIB_IRQCHIP on top of the revert of the previous
  buggy switchover. This time it works (hopefully).

Misc:

- Drop a FMC remnant file <linux/ipmi-fru.h>

- A slew of fixes.
