A set of pin control fixes for the v4.0 release cycle:

Browse source 
- Fix up consumer return values on pin control stubs.
 - Four patches fixing up the interrupt handling and
   sleep context save in the Baytrail driver.
 - Make default output directions work properly in the
   Cherryview driver.
 - Fix interrupt locking in the AT91 driver.
 - Fix setting interrupt generating lines as input in
   the sunxi driver.

Merge tag 'pinctrl-v4.0-2' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

Pull pin control fixes from Linus Walleij:
 "Here is a slew of pin control fixes I've accumulated for the v4.0
  kernel.  Nothing special, just driver fixes (mainly embedded Intel it
  seems) and a misunderstanding regarding the stub functions was
  reverted:

   - Fix up consumer return values on pin control stubs.
   - Four patches fixing up the interrupt handling and sleep context
     save in the Baytrail driver.
   - Make default output directions work properly in the Cherryview
     driver.
   - Fix interrupt locking in the AT91 driver.
   - Fix setting interrupt generating lines as input in the sunxi
     driver"

  pinctrl: sun4i: GPIOs configured as irq must be set to input before reading
  pinctrl: at91: move lock/unlock_as_irq calls into request/release
  pinctrl: update direction_output function of cherryview driver
  pinctrl: baytrail: Save pin context over system sleep
  pinctrl: baytrail: Rework interrupt handling
  pinctrl: baytrail: Clear interrupt triggering from pins that are in GPIO mode
  pinctrl: baytrail: Relax GPIO request rules
  Revert "pinctrl: consumer: use correct retval for placeholder functions"
