Jiri Pirko 7826d43f2d ethtool: fix drvinfo strings set in drivers
Use strlcpy where possible to ensure the string is \0 terminated.
Use always sizeof(string) instead of 32, ETHTOOL_BUSINFO_LEN
and custom defines.
Use snprintf instead of sprint.
Remove unnecessary inits of ->fw_version
Remove unnecessary inits of drvinfo struct.

Bill Pemberton 663e12e61d cpsw: remove __dev* attributes
CONFIG_HOTPLUG is going away as an option.  As result the __dev*
markings will be going away.

Remove use of __devinit, __devexit_p, __devinitdata, __devinitconst,

Richard Cochran 549985ee9c cpsw: simplify the setup of the register pointers
Instead of having a host of different register offsets in the device tree,
this patch simplifies the CPSW code by letting the driver set the proper
register offsets automatically, based on the CPSW version.

Vaibhav Hiremath 1fb19aa730 net: cpsw: Add parent<->child relation support between cpsw and mdio
CPGMAC SubSystem consist of various sub-modules, like, mdio, cpdma,
cpsw, etc... These sub-modules are also used in some of Davinci family
of devices. Now based on requirement, use-case and available technology
nodes the integration of these sub-modules varies across devices.

So coming back to Linux net driver, currently separate and independent
platform devices & drivers for CPSW and MDIO is implemented. In case of
Davinci they both has separate control, from resources perspective,
like clock.

In case of AM33XX, the resources are shared and only one register
bit-field is provided to control module/clock enable/disable, makes it
difficult to handle common resource.

So the solution here implemented in this patch is,

Create parent<->child relationship between both the drivers, making
CPSW as a parent and MDIO as its child and enumerate all the child nodes
under CPSW module.
Both the drivers will function exactly the way it was operating before,
including runtime-pm functionality. No change is required in MDIO driver
(for that matter to any child driver).

As this is only supported during DT boot, the parent<->child relationship
is created and populated in DT execution flow. The only required change
is inside DTS file, making MDIO as a child to CPSW node.

Daniel Mack 342b7b741d net: ti cpsw ethernet: set IFCTL_A bit in MACCONTROL
For RMII/RGMII mode operation in 100Mbps, the CPSW needs to set the
IFCTL_A bits in the MACCONTROL register. For all other PHY modes, this
bit is unused, so setting it unconditionally shouldn't cause any
trouble.
