Hi Catalin, Will and Arnd,

I just happened to find there is no SMMUv3 config in arm64 defconfig.

Maybe we should add it in defconfig or I miss something.

Thanks,
Zhou

It looks fine to me but it's usually the arm-soc guys picking the defconfig patches.

Is it OK for me to pick up this or will you directly pick up this? Thanks!

Either way works for me. I usually recommend platform maintainers picking up patches and then sending them on to arm at kernel.org, as that gets our attention quicker. A patch that gets sent with me personally on Cc might get lost in the email.
