From 86f15a5a6c13e1f01fd15975274f8e47458c185a Mon Sep 17 00:00:00 2001 From: Ben Wolsieffer Date: Wed, 1 Nov 2023 11:51:54 -0400 Subject: [PATCH] ARM: dts: stm32: add STM32F746 syscfg clock The syscfg syscon was missing its clock, therefore any attempt to read/write it after clk_disable_unused() silently failed. This was preventing external pin interrupts from working if they were initialized after this point.
