However, we have only seen few boards with RK3568 up to now, and I only got a couple of NanoPi R5C here to test, all with good hwrng results. Do you think it would be agreeable to only enable the HWRNG for RK3568 as suggested in this series? Or are we expecting quality to also vary as much as it (sadly) does for RK3566? _______________________________________________ Linux-rockchip mailing list Linux-rockchip@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-rockchip
