Merge tag 'gpio-v4.10-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio

Pull GPIO updates from Luinus Walleij:
 "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"
