From a4d65b701ffce52b69b5b6c3f253519129af182e Mon Sep 17 00:00:00 2001 From: BALATON Zoltan Date: Fri, 15 Oct 2021 03:06:20 +0200 Subject: vt82c686: Add a method to VIA_ISA to raise ISA interrupts MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Other functions in the VT82xx chips need to raise ISA interrupts. Keep a reference to them in the device state and add via_isa_set_irq() to allow setting their state.
