The network coprocessor (NetCP) is a hardware accelerator that processes
Ethernet packets. NetCP has a gigabit Ethernet (GbE) subsystem with a ethernet
switch sub-module to send and receive packets. NetCP also includes a packet
accelerator (PA) module to perform packet classification operations such as
header matching, and packet modification operations such as checksum
generation. NetCP can also optionally include a Security Accelerator(SA)
capable of performing IPSec operations on ingress/egress packets.

Keystone SoC's also have a 10 Gigabit Ethernet Subsystem (XGbE) which
includes a 3-port Ethernet switch sub-module capable of 10Gb/s and
1Gb/s rates per Ethernet port.

NetCP Subsystem device tree layout looks something like below:

-----------------------------
  NetCP subsystem(10G or 1G)
-----------------------------
	|
	|-> NetCP Devices ->	|
	|			|-> GBE/XGBE Switch
	|			|
	|			|-> Packet Accelerator
	|			|
	|			|-> Security Accelerator
	|
	|
	|
	|-> NetCP Interfaces ->	|
				|-> Ethernet Port 0
				|
				|-> Ethernet Port 1
				|
				|-> Ethernet Port 2
				|
				|-> Ethernet Port 3

Common driver supports GBE as well XGBE network processors.

The auto negotiation logic was geared to being the initiator of the
auto negotiation. This presented problems when auto negotiation was
initiated by the remote end. Change the auto negotiation logic to
make use of the auto negotiation event interrupt thus allowing the
auto negotiation state machine to function properly in either scenario.
This also removes the polling during auto-negotiation.

The QEMU open source machine emulator and virtualizer presents firmware
and operating systems running in virtual machines ("guests") with purely
virtual hardware (ie. hardware that has never existed in physical form).
Since QEMU exposes some of these devices in a DTB, it makes sense to
define "qemu" and "virtio" as vendor prefixes.

The qemu definition is from [1], revision 4451 (22:24, 25 November 2014).

The virtio definition is composed from [2] and [3].

Peter Maydell suggested that we describe new devices / DTB nodes in the
kernel Documentation tree that we expose to arm "virt" guests in QEMU.

Although the kernel is not required to access the fw_cfg interface,
"Documentation/devicetree/bindings/arm" is probably the best central spot
to keep the fw_cfg description in.

Current vendor-prefixes.txt already has "ak" prefix for Asahi Kasei Corp
by ae8c4209(of: Add vendor prefix for Asahi Kasei Corp.)

It went through the appropriate review process. But, almost all
Asahi Kasei chip drivers are using "asahi-kasei" prefix today.
(arch/arm/boot/dts/tegra20-seaboard.dts only is using "ak,ak8975",
 but there are instances of "asahi-kasei,ak8975" in other dts files.
 And drivers/iio/magnetometer/ak8975.c doesn't support "ak,ak8975" prefix)
So, we made a mistake there.

In addition, checkpatch.pl reports WARNING if it is using "asahi-kasei"
prerfix in DT file.
(DT compatible string vendor "asahi-kasei" appears un-documented)

Marking it deprecated and warning with checkpatch is certainly
preferable. So, this patch replace "ak" to "asahi-kasei" in
vendor-prefixes.txt. (and fixup tegra20-seaboard)

OTOH, Asahi Kasei is usually referred to as "AKM", but this patch
doesn't care about it. Because no DT is using that today.

Based on Arnds review comments here https://lkml.org/lkml/2014/11/13/161,
we should not be mixing address spaces in the reg property like this driver
currently does. This patch updates the driver, dt docs and also the existing
dt nodes to pass the sysconfig offset in the syscon dt property.

This patch breaks DT compatibility! But this platform is considered WIP,
and is only used by a few developers who are upstreaming support for it.
This change has been done as a single atomic commit to ensure it is
bisectable.

Based on Arnds review comments here https://lkml.org/lkml/2014/11/13/161,
update the miphy365 phy driver to access sysconfig register offsets via
syscfg dt property.

This is because the reg property should not be mixing address spaces
like it does currently for miphy365. This change then also aligns us
to how other platforms such as keystone and bcm7445 pass there syscon
offsets via DT.

Based on Arnds review comments here https://lkml.org/lkml/2014/11/13/161,
update the phy driver to not use the reg property to access the sysconfig
register offsets.

This is because other phy's (miphy28, miphy365) have a combination of
memory mapped registers and sysconfig control regs, and we shouldn't
be mixing address spaces in the reg property. In addition we would
ideally like the sysconfig offsets to be passed via DT in a uniform way.

This new method will also allow us to support devices which have sysconfig
registers in different banks more easily and it is also analagous to how
keystone and bcm7745 platforms pass there syscon offsets in DT.

This breaks DT compatibility, but this platform is considered WIP, and
is only used by a few developers who are upstreaming support for it.
