This patch series adds SMMU support to the SOCFPGA Stratix10 family
of parts. The addition of a clock parameter was required to ungate
the SMMU clock.
Please see the latest version of Vivek's runtime PM series[1] - there's
already been an awful lot of discussion over how to handle clocks, since
they're not part of the SMMU architecture and different implementations
can have very different requirements (and even different configurations
of the same implementation may vary, e.g. MMU-500 could technically have
up to 33 separate clocks).
Thanks,
Robin.
