Hm? Everything is here:
https://lore.kernel.org/all/20260413-orangepi-sd-card-uhs-v7-1-16650f49c022@gmail.com/

You can send individual patches to fix up threading, use --in-reply-to.

You already sent it on 13th of April. And now v8 the same day. Wait a
few days to allow people to actually review your code.

It's BTW merge window, so big series should slow down.
