Series | media: hantro: Trace hevc hw cycles performance register | expand |
Hi Benjamin, I'm confused: this is also part of '[PATCH v4 0/9] Additional features for Hantro HEVC', so do you want to merge this independently from that series? Are there differences between v4 1/9 and this patch, or are they identical? In any case, I'd like to have a Reviewed-by or Acked-by from Ezequiel before merging this.
