[ Upstream commit 11d827a993 ]
set_fipers() calling should be protected by spinlock in
case that any interrupt breaks related registers setting
and the function we expect. This patch is to move set_fipers()
to spinlock protecting area in ptp_gianfar_adjtime().

The gianfar driver has recently been enabled on arm64 but fails to build
since it check the return value of platform_get_irq() against NO_IRQ. Fix
this by instead checking for a negative error code.
Even on ARM where this code was previously being built this check was
incorrect since platform_get_irq() returns a negative error code which
may not be exactly the (unsigned int)(-1) that NO_IRQ is defined to be.

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.

Currently IEEE 1588 timer reference clock source is determined through
hard-coded value in gianfar_ptp driver. This patch allows to select ptp
clock source by means of device tree file node.
For instance:
fsl,cksel = <0>;
for using external (TSEC_TMR_CLK input) high precision timer
reference clock.
Other acceptable values:
<1> : eTSEC system clock
<2> : eTSEC1 transmit clock
<3> : RTC clock input
When this attribute isn't used, eTSEC system clock will serve as
IEEE 1588 timer reference clock.

Use the wrapper functions for getting and setting the driver data using
platform_device instead of using dev_{get,set}_drvdata() with &pdev->dev,
so we can directly pass a struct platform_device.
Also, unnecessary dev_set_drvdata() is removed, because the driver core
clears the driver data to NULL after device_release or on probe failure.

An early draft of the PHC patch series included an alarm in the

but the capability removal was overlooked. This patch fixes the issue
by advertising zero alarms.

When using a 36 bit dtb file, the driver complains "resource busy".
Investigating the source of the message leads one to the
gianfar_ptp_probe function.
Since the type of the device resource requested in this function
is IORESOURCE_MEM, it should use "iomem_resource" instead of
"ioports_resource".
