Reviewed-by: Edward O'Callaghan <funfunctor@xxxxxxxxxxxxxxxx>
Also, I just noticed cz_write_smc_sram_dword() and if I am not mistaken
they seems identical in both:
drivers/gpu/drm/amd/powerplay/smumgr/cz_smumgr.c and,
drivers/gpu/drm/amd/amdgpu/cz_smc.c
with a personal preference to the powerplay version I suppose.
Similar story with cz_send_msg_to_smc_async() *I think* but the
powerplay one uses some insane macro chain that dispatches to some
function called smum_wait_for_register_unequal(), quite hard to follow..
Any way, that is out of scope of the patch here.
Kind Regards,
Edward.
