...
Add the icc_sync_state callback to notify the framework when consumers
are probed and the bandwidth doesn't have to be kept at maximum anymore.

...
Common pattern of handling deferred probe can be simplified with
dev_err_probe(). Less code and the error value gets printed.

In case of error, the function of_parse_phandle() returns NULL pointer
not ERR_PTR(). The IS_ERR() test in the return value check should be
replaced with NULL test.

interconnect: Add imx core driver
...
This adds support for i.MX SoC family to interconnect framework.
Platform drivers can describe the interconnect graph and several
adjustment knobs where icc node bandwidth is converted to a
DEV_PM_QOS_MIN_FREQUENCY request.
The interconnect provider is probed through the main NOC device and
other adjustable nodes on the same graph are found from a
fsl,scalable-nodes phandle array property.
