From 74fbc7d371d9a438b8e39d926d9d5012d2f762c4 Mon Sep 17 00:00:00 2001 From: Song Hongyan Date: Tue, 11 Dec 2018 09:58:23 +0800 Subject: HID: intel-ish-hid: add MSI interrupt support Now ish hid ipc only support sideband interrupt but on some platforms they use MSI interrupt. In order to make the interrupt type coverage all the scenario add single MSI interrupt support, it can match all interrupt types.
