Your Reviewed-by tags were on the initial i.MX8qxp Display Controller driver patches. And, those patches have already landed. Now, I'm waiting for Acked-by or Reviewed-by tags on those driver patches which add i.MX8qxp Display Controller *prefetch engines* support. 'b4 trailers -u' doesn't include any Reviewed-by from you on those patches... I sent v6 prefetch engine patch series[1] just now. It would be great to have your Acked-by or Reviewed-by tags on those driver patches :) [1] https://lore.kernel.org/all/[email protected]/ > > Maxime > -- > linux-phy mailing list > [email protected] > https://lists.infradead.org/mailman/listinfo/linux-phy -- Regards, Liu Ying
