Subject: [PATCH] drm/amdgpu: add DMUB outbox event IRQ source define/complete/debug flag
Date: Tue, 6 Apr 2021 14:42:55 +0800	[thread overview]
Message-ID: <20210406064255.45212-1-shenshih@amd.com> (raw)

[Why & How]
We use outbox interrupt that allows us to do the AUX via DMUB
Therefore, we need to add some irq source related definition
in the header files;
Also, I added debug flag that allows us to turn it on/off
for testing purpose.
