Merge tag 'pinctrl-v3.7-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl 

Pull pinctrl fixes from Linus Walleij:
 "This fixes a few pinctrl problems seen since v3.7-rc1:
   - Section tagging for init code
   - Use proper pointers to lookup struct device * in the bcm2835
     (a.k.a.  Raspberry Pi)
   - Remove duplicate #includes
   - Fix bad return values in errorpath
   - Remove extraneous pull function from the sirf driver causing build
     errors
   - Provide compilation stubs for the Nomadik pinctrl driver when used
     with legacy systems without PRCMU units
   - Various irqdomain fixes in the Nomadik driver as predicted
   - Various smallish bugs in the Tegra driver, most also targeted for
     stable
   - Removed a deadlocking mutex in the groups debugfs show function"

* tag 'pinctrl-v3.7-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl:
  pinctrl/nomadik: pass DT node to the irqdomain
  pinctrl/nomadik: use zero as default irq_start
  pinctrl: fix missing unlock on error in pinctrl_groups_show()
  pinctrl/nomadik: use irq_create_mapping()
  pinctrl: remove mutex lock in groups show
  pinctrl: tegra: correct bank for pingroup and drv pingroup
  pinctrl: tegra: set low power mode bank width to 2
  dt: Document: correct tegra20/30 pinctrl slew-rate name
