Sorry for the delay in replying to this -- Robin's been reworking the driver
so that implementation quirks can be specified more cleanly. Please can you
take a look at:

https://git.kernel.org/pub/scm/linux/kernel/git/will/linux.git/log/?h=for-joerg/arm-smmu/refactoring

and try to respin your patches on top of that?

Thanks,

Will
