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. Regards Alex Alexandre TORGUE (8): pinctrl: stm32: fix bad location of gpiochip_lock_as_irq pinctrl: stm32: use gpio-ranges to declare bank range
I just see typo issue in patch 1&2. I will send a V2 when more review will be done.
