Hi!

Hi Steffen,

This series adds support for the SoCFPGA L3 NIC. As the memory range has
a lot of holes, where you can not read from, syscon can not be used for
this IP core. Instead add a new driver, that knows about all the allowed
ranges and guards the access via regmap.

I note that while this series plumbs in a set of accessors (via regmap),
there are no users as part of this series. What exactly do you intend to
use these for? What is going to (re)program the bus, and how?

I also note that you mention this L3/L4 bus hierarchy is composed of a
number of NIC-301s, rather than being a single custom IP block. If
that's the case, it would seem like there should be a binding for the
NIC-301, and the hierarchy should be described.

Thanks,
Mark.

Changes in v3:

	- Split out the devicetree binding in its own patch

Regards,
Steffen
