[PATCH v2 0/7] Add STM32F469 pinctrl and fix issues in STM32 pinctrl
From: Alexandre TORGUE
Date: Fri Apr 07 2017 - 08:45:02 EST
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
