[PATCH v3 12/27] drm/amd/display: dce_dmcu: add DCE6 specific macros, functions

Mauro Rossi issor.oruam at gmail.com
Thu Jul 16 21:22:36 UTC 2020


[Why]
DCE6 has no SMU_INTERRUPT_CONTROL register, but it's used for DCN10 and later

[How]
Add DCE6 specific macros definitions for DMCU registers and masks
DCE6 DMCU macros will avoid buiding errors when using DCE6 headers
There is no other change needed in dce_dcmu
