Fair point. I wasn't fully aware that an active user base was a strict
requirement for upstreaming a new driver, but that completely makes
sense from a maintenance perspective.

I'll hold off on pushing this driver for now until mbedtee gains more
actual users. For what it's worth, the integration side is fully in
place with tested QEMU/FastModel support and a working Buildroot
overlay, so it's very easy for anyone interested to try it out.

Thanks for your time and the prompt review!

Cheers,
Xing
