[GIT,PULL] GPIO bulk changes for v4.10

Hi Linus,

here is the bulk of the GPIO changes for the v4.10 series.

I had some screwups in linux-next last week but ironed it out,
but in case you wonder why there are two relatively young
immutable branches (pl061 and thread-irq-simpler) merged in
dec 7 it's because of fixing that mess. It has since been tested
in linux-next.

The two immutable branches have cross dependencies to pin
control so they will appear in that pull request as well.

Please pull it in! Technical details are in the signed tag.

Yours,
Linus Walleij

  Merge branch 'thread-irq-simpler' into devel (2016-12-07 15:24:12 +0100)

----------------------------------------------------------------
Bulk GPIO changes for the v4.10 kernel cycle:

Core changes:

- Simplify threaded interrupt handling: instead of passing
  numbed parameters to gpiochip_irqchip_add_chained() we
  create a new call: gpiochip_irqchip_add_nested() so the two
  types are clearly semantically different. Also make sure
  that all nested chips call gpiochip_set_nested_irqchip()
  which is necessary for IRQ resend to work properly if
  it happens.

- Return error on seek operations for the chardev.

- Clamp values set as part of gpio[d]_direction_output() so
  that anything != 0 will be send down to the driver as "1"
  not the value passed in.

- ACPI can now support naming of GPIO lines, hogs and holes
  in the GPIO lists.

New drivers:

- The SX150x driver was deemed unfit for the GPIO subsystem
  and was moved over to a combined GPIO+pinctrl driver in the
  pinctrl subsystem.

New features:

- Various cleanups to various drivers.
