From 29786d42ba4ab6a70d3055083512e0bdd8e2f9ec Mon Sep 17 00:00:00 2001 From: Mark Cave-Ayland Date: Sat, 28 May 2022 10:02:11 +0100 Subject: [PATCH] hw/acpi/piix4: use qdev gpio to wire up sci_irq MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Introduce piix4_pm_init() instance init function and use it to initialise the separate qdev gpio for the SCI IRQ. The sci_irq can now be wired up directly using a qdev gpio instead of having to set the IRQ externally in piix4_pm_initfn().
