4986b4f008 ptp: drivers: set the number of programmable pins.
This patch updates the many PTP Hardware Clock drivers with the
newly introduced field that advertises the number of programmable
pins. Some of these devices do have programmable pins, but the
implementation will have to wait for follow on patches.

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.

ca162a82f5 fec: Only pass pdev in fec_ptp_init()
Passing pdev in fec_ptp_init() is enough, since we can get ndev locally.

31b7720c82 fec: Convert printks to netdev_<level>
Use a more current logging message style.

Convert the printks where a struct net_device is available to
netdev_<level>.  Convert the other printks to pr_<level> and
add pr_fmt where appropriate.

eb1d064058 fec: Fix PHC device log
Currently when booting a mx6 device we get the following on boot:

registered PHC device on eth%d

Fix it by printing the network device name only after it gets registered, so
that the following can be read now:

fec 2188000.ethernet eth0: registered PHC device 0

9d73adf431 fec: Fix the build as module
Since commit ff43da86c6 (NET: FEC: dynamtic check DMA desc buff type) the
following build error happens when CONFIG_FEC=m

ERROR: "fec_ptp_init" [drivers/net/ethernet/freescale/fec.ko] undefined!
ERROR: "fec_ptp_ioctl" [drivers/net/ethernet/freescale/fec.ko] undefined!
ERROR: "fec_ptp_start_cyclecounter" [drivers/net/ethernet/freescale/fec.ko] undefined!

Fix it by exporting the required fec_ptp symbols.

85bd1798b2 net: fec: fix spin_lock dead lock
=========================================================
[ INFO: possible irq lock inversion dependency detected ]
3.8.0-rc5+ #82 Not tainted
---------------------------------------------------------
swapper/0/0 just changed the state of lock:
 (&(&fep->hw_lock)->rlock){..-...}, at: [<8034e2f8>] fec_enet_start_xmit+0x48/0x                      2cc
but this lock took another, SOFTIRQ-unsafe lock in the past:
(prepare_lock){+.+.+.}

and interrupts could create inverse lock ordering between them.
other info that might help us debug this:
Possible interrupt unsafe locking scenario:

CPU0				CPU1
----				----
lock(prepare_lock);
				local_irq_disable()
				lock(&(&fep->hw_lock)->rlock);
				lock(prepare_lock);
<Interrupt>
lock(&(&fep->hw_lock)->rlock);

*** DEADLOCK ***

move below calculate out of spin lock section
	diff = fep->cc.mult;
	diff *= ppb;
	diff = div_u64(diff, 1000000000ULL);

diff is local variable and not neccesary in spin lock

6605b730c0 FEC: Add time stamping code and a PTP hardware clock
This patch adds a driver for the FEC(MX6) that offers time
stamping and a PTP haderware clock. Because FEC\ENET(MX6)
hardware frequency adjustment is complex, we have implemented
this in software by changing the multiplication factor of the
timecounter.
