From e9c17d91e6980993711eebe0c914fbd31298b94e Mon Sep 17 00:00:00 2001 From: Antonio Borneo Date: Mon, 15 Apr 2024 15:49:17 +0200 Subject: [PATCH] dt-bindings: interrupt-controller: stm32-exti: Add irq mapping to parent The mapping of EXTI events to its parent interrupt controller is both SoC and instance dependent. The current implementation requires adding a new mapping table to the driver's code and a new compatible for each new EXTI instance. To avoid that use the interrupts-extended property to list, for each EXTI event, the associated parent interrupt.
