This fixes a few pinctrl problems seen since v3.7-rc1:

Browse Source 
- 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
