Linus Torvalds 061ad5038c 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.
