Subject: [GIT PULL] Bulk GPIO changes for the v5.1 kernel cycle

Hi Linus,

here is the bulk of the GPIO changes for the v5.1 kernel cycle.
I'm very happy to get this merged now because the development
has been all over the place, all is properly ACKed as far as possible
and has been merging and compiling nicely in linux-next but it
still makes me nervous to have it lying around on different immutable
branches and what not.

The signed tag describes what the changes are about. We have
some hunks hitting x86 platform code, generic irqchip, ARM device
trees and machines, pin control and even device core. The respective
subsystem maintainers have been involved and ACKed the patches.

Please pull it in for v5.1!

Yours,
Linus Walleij

  gpio: pca953x: Fix dereference of irq data in shutdown (2019-03-01
11:55:32 +0100)

----------------------------------------------------------------
This is the bulk of GPIO changes for the v5.1 cycle:

Core changes:

- The big change this time around is the irqchip handling in
  the qualcomm pin controllers, closely coupled with the
  gpiochip. This rework, in a classic fall-between-the-chairs
  fashion has been sidestepped for too long. The Qualcomm
  IRQchips using the SPMI and SSBI transport mechanisms have
  been rewritten to use hierarchical irqchip. This creates
  the base from which I intend to gradually pull support for
  hierarchical irqchips into the gpiolib irqchip helpers to
  cut down on duplicate code. We have too many hacks in the
  kernel because people have been working around the missing
  hierarchical irqchip for years, and once it was there,
  noone understood it for a while. We are now slowly adapting
  to using it. This is why this pull requests include changes
  to MFD, SPMI, IRQchip core and some ARM Device Trees
  pertaining to the Qualcomm chip family. Since Qualcomm have
  so many chips and such large deployments it is paramount
  that this platform gets this right, and now it (hopefully)
  does.

- Core support for pull-up and pull-down configuration, also
  from the device tree. When a simple GPIO chip support a
  "off or on" pull-up or pull-down resistor, we provide a
  way to set this up using machine descriptors or device tree.
  If more elaborate control of pull up/down (such as
  resistance shunt setting) is required, drivers should be
  phased over to use pin control. We do not yet provide a
  userspace ABI for this pull up-down setting but I suspect
  the makers are going to ask for it soon enough. PCA953x
  is the first user of this new API.

- The GPIO mockup driver has been revamped after some
  discussion improving the IRQ simulator in the process.
  The idea is to make it possible to use the mockup for
  both testing and virtual prototyping, e.g. when you do
  not yet have a GPIO expander to play with but really
  want to get something to develop code around before
  hardware is available. It's neat. The blackbox testing
  usecase is currently making its way into kernelci.

- ACPI GPIO core preserves non direction flags when updating
  flags.

- A new device core helper for devm_platform_ioremap_resource()
  is funneled through the GPIO tree with Greg's ACK.

New drivers:

- TQ-Systems QTMX86 GPIO controllers (using port-mapped
  I/O)

- Gateworks PLD GPIO driver (vaccumed up from OpenWrt)

- AMD G-Series PCH (Platform Controller Hub) GPIO driver.

- Fintek F81804 & F81966 subvariants.

- PCA953x now supports NXP PCAL6416.

Driver improvements:

- IRQ support on the Nintendo Wii (Hollywood) GPIO.

- get_direction() support for the MVEBU driver.

- Set the right output level on SAMA5D2.

- Drop the unused irq trigger setting on the Spreadtrum
  driver.

- Wakeup support for PCA953x.

- A slew of cleanups in the various Intel drivers.
