From 136fdfdad2170ef87d5991613f925b61e1cbe483 Mon Sep 17 00:00:00 2001 From: Potin Lai Date: Sat, 23 May 2026 10:28:07 +0800 Subject: [PATCH] ARM: dts: aspeed: sanmiguel: Add IOEXP interrupt pin settings Kernel dmesg reports IRQ #44 being disabled due to unhandled interrupts from multiple PCA953x IO expanders: [ 447.047861] irq 44: nobody cared (try booting with the "irqpoll" option) [ 447.063124] handlers: [ 447.068176] [<2ab869ad>] irq_default_primary_handler threaded [] pca953x_irq_handler [ 447.087268] [<2ab869ad>] irq_default_primary_handler threaded [] pca953x_irq_handler [ 447.106344] [<2ab869ad>] irq_default_primary_handler threaded [] pca953x_irq_handler [ 447.125421] [<2ab869ad>] irq_default_primary_handler threaded [] pca953x_irq_handler [ 447.144513] [<2ab869ad>] irq_default_primary_handler threaded [] pca953x_irq_handler [ 447.163587] [<2ab869ad>] irq_default_primary_handler threaded [] pca953x_irq_handler [ 447.182663] [<2ab869ad>] irq_default_primary_handler threaded [] pca953x_irq_handler [ 447.201756] [<2ab869ad>] irq_default_primary_handler threaded [] pca953x_irq_handler [ 447.220837] Disabling IRQ #44 The affected IOEXP nodes are missing interrupt pin configuration in the device tree, causing the interrupt line to remain asserted and resulting in repeated unhandled IRQ events. Add the required interrupt-related properties for the affected IOEXP devices to ensure proper interrupt handling and prevent the IRQ from being disabled.
