pinctrl: Add STM32 MCUs support This patch adds pinctrl and GPIO support to STMicroelectronic's STM32 family of MCUs. While it only supports STM32F429 for now, it has been designed to enable support of other MCUs of the family (e.g. STM32F746).

pinctrl: Add IRQ support to STM32 gpios This patch adds IRQ support to STM32 gpios. The EXTI controller has 16 lines dedicated to GPIOs. EXTI line n can be connected to only line n of one of the GPIO ports, for example EXTI0 can be connected to either PA0, or PB0, or PC0... This port selection is done by specifying the port number into System Config registers.

pinctrl: stm32: add IRQ_DOMAIN_HIERARCHY dependency The newly added irqchip support for the stm32 pinctrl driver uses hierarchical IRQ domains as provided by the NVIC primary irqchip. This works great for any configuration that may be relevant on stm32, but when doing compile-testing (randconfig), we can enable it without NVIC or any other primary irqchip that enables IRQ_DOMAIN_HIERARCHY: drivers/pinctrl/stm32/pinctrl-stm32.c:212:13: error: 'irq_chip_eoi_parent' undeclared here (not in a function) drivers/pinctrl/stm32/pinctrl-stm32.c:213:20: error: 'irq_chip_mask_parent' undeclared here (not in a function) drivers/pinctrl/stm32/pinctrl-stm32.c:214:20: error: 'irq_chip_unmask_parent' undeclared here (not in a function) drivers/pinctrl/stm32/pinctrl-stm32.c:215:20: error: 'irq_chip_set_type_parent' undeclared here (not in a function) This adds a Kconfig dependency to limit compile-testing to configurations that have IRQ_DOMAIN_HIERARCHY already enabled. It's not obvious whether we should use 'depends on' or 'select' here, I think either one works, with 'depends on' being more intuitive, while 'select' would be less likely to cause dependency loops.
