From 52719d90c209185ee13475539d7d68be7ebb16cd Mon Sep 17 00:00:00 2001 From: Martin Schiller Date: Fri, 12 Apr 2024 08:56:24 +0200 Subject: [PATCH] lantiq: ltq-ptm: use platform_get_irq to get irqs This is required for linux-6.1 compatibility. IRQs are not automatically mapped from HW to virtual IRQ numbers when the IRQ domain is registered. This happens when the IRQ number is read from the device tree based on the IRQ domain from the device tree now. In kernel 5.15 it was done when the IRQ domain was registered.
