Create an API to match voltages across asymmetric CPUs as
this can be useful in systems with a shared rail across CPUs.
The API takes in one input argument which is the frequency of
a big cluster CPU for which a voltage-equivalent little cluster
CPU frequency is desired. The return value is this little
cluster CPU frequency. All frequencies are in units of kHz.

If page fault handler is triggered from within the same context
as ARM IOMMU driver, it can lead to deadlock due to improper
grabbing of mutexes.
This can be avoided if the page fault handler context is
immediately returned to ARM IOMMU driver after scheduling
work queue for triggering client specific fault handler
registered with CAM SMMU driver.
So, schedule tasklet for triggering page fault handler of all
registered clients.

A recent change in the ARM SMMU driver expects either a 0 or an
-EBUSY from any of the registered page fault handlers. Otherwise
it will assume the page fault unhandled and trigger a fatal crash.
So unless the various context bank page fault handlers are updated
to return either a 0 or an -EBUSY, each page fault will trigger a
fatal crash. This will make debugging the underlying problem
causing the page fault in the first place, more difficult.
So fix the page fault handler to return proper error code so that
ARM SMMU driver does not consider the page fault unhandled and the
device does not crash.
