[PATCH] drm/amdgpu: add DMUB outbox event IRQ source define/complete/debug flag

Jude Shih shenshih at amd.com
Tue Apr 6 06:42:55 UTC 2021


[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.
