Is there another patch adding driver support for matching this new binding?

Nope. But the compatible is used as a fallback with "arm,mmu-500". The
dts patch is merged into qcom tree:

https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux.git/commit/?h=dts-for-5.12&id=a2bdfdfba2afb532f2a2c8082bdb7de8379a4b6c

Thanks,
