Subject: drm/amd/pm: Add ASIC independent throttle bits
X-Git-Tag: v5.15~765^2~10^2~70
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=1049de4305ecc281367fc4e614c013b6c21a4d7f;p=platform%2Fkernel%2Flinux-starfive.git

drm/amd/pm: Add ASIC independent throttle bits

Add new defines for thermal throttle status bits which are ASIC
independent. This bit field will be visible to userspace via
gpu_metrics alongside the previous ASIC dependent bit fields. Seperated
into four types: power throttlers (16 bits), current throttlers (16
bits), temperature (24 bits), other (8 bits).
