Ioana Ciornei 69651bd8d3 soc: fsl: dpio: add Net DIM integration
Use the generic dynamic interrupt moderation (dim) framework to
implement adaptive interrupt coalescing on Rx. With the per-packet
interrupt scheme, a high interrupt rate has been noted for moderate
traffic flows leading to high CPU utilization.

The dpio driver exports new functions to enable/disable adaptive IRQ
coalescing on a DPIO object, to query the state or to update Net DIM
with a new set of bytes and frames dequeued.

help
The global utilities block controls power management, I/O device
enabling, power-onreset(POR) configuration monitoring, alternate
function selection for multiplexed signals,and clock control.
This driver is to manage and access global utilities block.
Initially only reading SVR and registering soc device are supported.
Other guts accesses, such as reading RCW, should eventually be moved
into this driver as well.

Driver for the DPAA2 DPIO object. A DPIO provides queue and
buffer management facilities for software to interact with
other DPAA2 objects. This driver does not expose the DPIO
objects individually, but groups them under a service layer
API.

Console driver for DPAA2 platforms. Exports 2 char devices,
/dev/dpaa2_mc_console and /dev/dpaa2_aiop_console,
which can be used to dump the Management Complex and AIOP
firmware logs.

help
The NXP QorIQ Processors based on ARM Core have RCPM module
(Run Control and Power Management), which performs all device-level
tasks associated with power management, such as wakeup source control.
Note that currently this driver will not support PowerPC based
QorIQ processor.
