Subject: [PATCH v2 1/8] drm/amd/pm: Add u64 throttler status field to
gpu_metrics
This patch piggybacks off the gpu_metrics_v1_3 bump and adds a new ASIC
independant u64 throttler status field (indep_throttle_status).
Similarly bumps gpu_metrics_v2 version (to v2_2) to add field. The alternative
to adding this new field would be to overwrite the original u32 throttle_status
(would still require a version bump for gpu_metrics_v2). The benefit to adding
a new field is that we can allocate 16 bits to each "type" of throttler
information and have more leeway for adding additional throttler bits in the
future.
