From 6aa439ca33be766ec35b6fc3d851f4b5c8930fb3 Mon Sep 17 00:00:00 2001
From: David Panariti <David.Panariti@amd.com>
Date: Tue, 22 May 2018 14:25:49 -0400
Subject: [PATCH 4637/5725] drm/amdgpu: Add plumbing for handling SQ EDC/ECC
interrupts v2.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
SQ can generate interrupts and installs the ISR to
handle the SQ interrupts.
Add parsing SQ data in interrupt handler.
v2:
Remove CZ only limitation.
Rebase.
