This patch series add support for loadavg values for GPU
sub-components. I am adding a SMA algorithm as I was not
really sure if EWMA would be a good fit for this use case.

Changes v2:
 - Addressed feedback from Lucas

Christian Gmeiner (4):
  drm/etnaviv: add simple moving average (SMA)
  drm/etnaviv: add loadavg accounting
  drm/etnaviv: show loadavg in debugfs
  drm/etnaviv: export loadavg via perfmon
