[PATCH v2 0/7] Add STM32F469 pinctrl and fix issues in STM32 pinctrl

[Alexandre TORGUE]

This series adds support of a dedicated driver for STM32F469 MCU pinctroller.
This add generates some changes inside STM32 pinctrl driver and inside STM32
device tree.

Changes in STM32 pinctrl driver:
-------------------------------
	
	- Add STM32F469 driver.
	
	- Change STM32 pinctrl core in order to use "gpio-ranges" devicetree definitions.
	  Indeed, on STM32F469 there an hole in BANK J. We need to declare a gpio-ranges
	  in gpioj controller node to handle this hole.

Changes in STM32 device tree:
----------------------------
I propose a new architecture (a new file split) for pinmux definition:
	
	- Create a common stm32f4-pinctrl.dtsi for pinmuxing definitions
	  which are common between STM32F429 and STM32F469 MCU. 
	
	- Create dedicated stm32fxxx-pinctrl.dtsi file for each MCU
	  (stm32f429-pinctrl.dtsi and stm32f469-pinctrl.dtsi) each one will
	  include stm32f4-pinctrl.dtsi. All differences (pinmuxing or GPIO
	  bank holes) will be put inside the dedicated files.

This series fix a locking issue when a gpio is used as IRQ.

Changes since v1:
 -Rebase on 4.11-rc1.
 -Fix issues for "gpio-ranges" patch.

Regards
Alex
