Pramod Kumar f20e6657a8 mdio: mux: Enhanced MDIO mux framework for integrated multiplexers
An integrated multiplexer uses same address space for
"muxed bus selection" and "generation of mdio transaction"
hence its good to register parent bus from mux driver.

Hence added a mechanism where mux driver could register a
parent bus and pass it down to framework via mdio_mux_init api.

Julia Lawall 0286234187 net: phy: mdio: add missing of_node_put
for_each_available_child_of_node performs an of_node_get on each iteration, so
a break out of the loop requires an of_node_put.

A simplified version of the semantic patch that fixes this problem is as
follows (http://coccinelle.lip6.fr):

// <smpl>
@@
expression root,e;
local idexpression child;
@@

 for_each_available_child_of_node(root, child) {
   ... when != of_node_put(child)
       when != e = child
(
   return child;
|
+  of_node_put(child);
?  return ...;
)
   ...
 }
// </smpl>

Wolfram Sang 9aec7aeced net: phy: drop owner assignment from platform_drivers
A platform_driver does not need to set an owner, it will be populated by the
driver core.

Paul Gortmaker a81ab36bf5 drivers/net: delete non-required instances of include <linux/init.h>
None of these files are actually using any __init type directives
and hence don't need to include <linux/init.h>.   Most are just a
left over from __devinit and __cpuinit removal, or simply due to
code getting copied from one driver to the next.

This covers everything under drivers/net except for wireless, which
has been submitted separately.

Bill Pemberton 633d159497 net/phy: 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,
and __devexit.

Timur Tabi 16fa9e1d10 netdev/phy: mdio-mux-mmioreg.c should include of_address.h
mdio-mux-mmioreg.c uses function of_address_to_resource(), which is defined
in linux/of_address.h.  This fixes a compilation error:

Timur Tabi 6cc2ff8249 netdev/phy: add MDIO bus multiplexer driven by a memory-mapped device
Add support for an MDIO bus multiplexer controlled by a simple memory-mapped
device, like an FPGA.  The device must be memory-mapped and contain only
8-bit registers (which keeps things simple).

Tested on a Freescale P5020DS board which uses the "PIXIS" FPGA attached
to the localbus.
