We can select which events we know will be active based on the current frequency versus our imposed range, i.e. if at minimum, we know we will not want to generate any more down-interrupts and vice versa. v2: We only need the TIMEOUT when above min frequency. v3: Tweak VLV at the same time Signed-off-by: Chris Wilson Cc: Deepak S Reviewed-by:Deepak S Signed-off-by: Daniel Vetter --- Reading git-diff-tree failed
