Merge branch 'samsung/pinctrl' into next/soc 

From Kukjin Kim:
Here is Samsung DT for v3.8 and this is including DT for EXYNOS4X12
SoC, SMDK4412 board, pinctrl for exynos4x12, TMU, MFC, SATA and SATA
PHY.

As I commented on [4/7], this branch merged pinctrl/samsung to support
pinctrl for exynos4x12 without useless merge conflicts.

* samsung/pinctrl:
  pinctrl: samsung: Update error check for unsigned variables
  pinctrl: samsung: Add support for EXYNOS4X12
  Documentation: Update samsung-pinctrl device tree bindings documentation
  pinctrl: samsung: Add GPIO to IRQ translation
  pinctrl: exynos: Set pin function to EINT in irq_set_type of wake-up EINT
  pinctrl: samsung: Use per-bank IRQ domain for wake-up interrupts
  pinctrl: samsung: Use one GPIO chip per pin bank
  pinctrl: exynos: Use one IRQ domain per pin bank
  pinctrl: samsung: Include bank-specific eint offset in bank struct
  pinctrl: samsung: Hold pointer to driver data in bank struct
  pinctrl: samsung: Match pin banks with their device nodes
  ARM: dts: exynos4210-pinctrl: Add nodes for pin banks
  pinctrl: samsung: Distinguish between pin group and bank nodes
  pinctrl: samsung: Remove static pin enumerations
  pinctrl: samsung: Assing pin numbers dynamically
  pinctrl: samsung: Do not pass gpio_chip to pin_to_reg_bank
  pinctrl: samsung: Detect and handle unsupported configuration types

   multiplexing) must contain following properties:



   - interrupt-parent: phandle of the interrupt parent to which the external

   - interrupts: interrupts of the interrupt parent which are used for external

All the pin controller nodes should be represented in the aliases node using

the following format 'pinctrl{n}' where n is a unique number for the alias.
