affine its interrupt to CPU 0. If the CPU is later brought online
the hotplug handler will correctly adjust the affinity.

Change the mapping of the QBMan cache enabled area from using ioremap_wc()
to memremap(). This allows the __iomem attribute to be removed from the
pointer (which makes sense as accesses try this as cacheable memory not
IO memory). These changes allow sparse checks to pass.

When shutting down a FQ on a dedicated channel only the
SW portal associated with that channel can dequeue from it.
Make sure the correct portal is use.

The drain_mr_fqni() function may be called fron uninterruptable
context so convert the msleep() to an mdelay(). Also ensure that
the valid bit is updated while polling.

Clean the BMan buffer pools if the device had been initialized
previously. This will ensure a consistent state if the kernel
was soft restarted (kexec for example)

If the QMan device was previously initialized make sure all the
frame queues are out of service once all the portals are probed.
This handles the case where the kernel is restarted without the
SoC being reset (kexec for example)

The timeout for QBMan Management Commands can falsely trigger on a
busy system. This patch doubles the timeout to avoid the
false error reports

The DPIO service interface handles initialization of DPIO objects
and exports APIs to be used by other DPAA2 object drivers to perform
queuing and buffer management related operations. The service allows
registration of callbacks when frames or notifications are received
The DPIO driver registers with the fsl-mc bus to handle bus-related
events for DPIO objects. Key responsibility is mapping I/O
regions, setting up interrupt handlers, and calling the DPIO
service initialization during probe.
