The previous diolan adapter uses other out/in endpoints than
the current DLN-2-U2C in compatibility mode.
They changed from 0x2/0x84 to 0x3/0x83.
This patch gets the endpoints from the usb interface, instead
of hardcode them in the driver.
This was tested on a current DLN-2-U2C board.

I2C IP block expect LE data, but CPU may operate in BE mode.
Need to use endian neutral functions to read/write h/w registers.
I.e instead of __raw_read[lw] and __raw_write[lw] functions code
need to use read[lw]_relaxed and write[lw]_relaxed functions.
If the first simply reads/writes register, the second will byteswap
it if host operates in BE mode.
Changes are trivial sed like replacement of __raw_xxx functions

This happend with SLES11SP2 Lustre client, which in turn acts as an
NFS server, exporting a subtree of an Lustre fs through NFS.
We detected that whenever we are writing to a new file using, fx,
'echo blah > newfile', it will return ENOENT error. We found
out that this was caused by the anonymous dentry. In SLESS11SP2,
anonymous dentries are assigned '/' as the name, instead of an
empty string. When MDT handles the intent_open call, it will look
up the obj by the name if it is not an empty string, and thus
couldn't find it.
As MDS_OPEN_BY_FID is always set on this request, we never need
to send the name in this request. The fid is already available
and should be used in case the file has been renamed.

First set of new features, drivers and cleanups for IIO in the 3.14 cycle.
This mostly consists of patches that didn't quite make the last cycle. Lots
of interesting things under review currently.
Core:
- Add devm_iio_device_register/unregister. I took some convincing on whether
there would be many devices that really were simple enough to need no
explicit actions on removal. Turns out there are some.
- Move some stray docs to above the relevant implemenation.
- Drop a redundant repeated check on the fact the trigger has actually changed
when there is a userspace attempt change it.
Drivers:
New drivers
- Freescale MPL3115A2 Pressure / temperature sensor
New functionality
- hid_sensors: add sensitivity support.
DT bindings
- tsl2563
- hmc5843
Cleanups
- Drop unused scan_type from viperboard adc driver.
- devm_iio_device_register used in viperboard, ad5421, ad5755, adis16130,
adxrs450, vcnl4000, adis16220, ad7816, lpc32xx, adt7316, adis16060, isl29018
and ad2s1200. Note that this was proposed in a number of other drivers
and this revealed a number of missorderings in remove functions. Also for
now I have blocked this on any device that any hardware suspend suport on
the basis that we probably want to power down devices if they have no driver
support loaded.
For exmaple, keycode: KEY_OK(0x160) is changed by "and" operation with
KEY_MAX(0x2ff) to KEY_KPENTER(96).

quirk to make eMMC work with device tree.
It seems that mostly vaux3 is used, and only some earlier revisions
used vmmc2. This has been tested to work on devices where the
system_rev passed by the bootloader has versions 0x0010, 0x2101

This patch implements the power_down_finish() method for TC2, to
enable the kernel to confirm when CPUs are safely powered down.
The information required for determining when a CPU is parked
cannot be obtained from any single place, so a few sources of
information must be combined:
* mcpm_cpu_power_down() must be pending for the CPU, so that we
don't get confused by false STANDBYWFI positives arising from
CPUidle. This is detected by waiting for the tc2_pm use count
for the target CPU to reach 0.
* Either the SPC must report that the CPU has asserted
STANDBYWFI, or the TC2 tile's reset control logic must be
holding the CPU in reset.
Just checking for STANDBYWFI is not sufficient, because this
signal is not latched when the the cluster is clamped off and
powered down: the relevant status bits just drop to zero. This
means that STANDBYWFI status cannot be used for reliable
detection of the last CPU in a cluster reaching WFI.
This patch is required in order for kexec to work with MCPM on TC2.
MCPM code was changed in commit 0de0d64675 ('ARM: 7848/1: mcpm:
Implement cpu_kill() to synchronise on powerdown'), and since then it
will hit a WARN_ON_ONCE() due to power_down_finish not being implemented
on the TC2 platform.

(Mika Westerberg sees them too in his tests).
Some investigation documented in kernel bug #65281 led me to the
conclusion that the source of the problem is the device_del() in
pci_stop_dev() as it now causes the sysfs directory of the device to be
removed recursively along with all of its subdirectories. That includes
the sysfs directory of the device's subordinate bus (dev->subordinate) and
its "power" group.
Consequently, when pci_remove_bus() is called for dev->subordinate in
pci_remove_bus_device(), it calls device_unregister(&bus->dev), but at this
point the sysfs directory of bus->dev doesn't exist any more and its
"power" group doesn't exist either. Thus, when dpm_sysfs_remove() called
from device_del() tries to remove that group, it triggers the above
warning.
That indicates a logical mistake in the design of
pci_stop_and_remove_bus_device(), which causes bus device objects to be
left behind their parents (bridge device objects) and can be fixed by
moving the device_del() from pci_stop_dev() into pci_destroy_dev(), so
pci_remove_bus() can be called for the device's subordinate bus before the
device itself is unregistered from the hierarchy. Still, the driver, if
any, should be detached from the device in pci_stop_dev(), so use
device_release_driver() directly from there.

.probe method).
961da7fb6b22 ("PCI: Avoid unnecessary CPU switch when calling driver

When the system enters suspend, it disables all interrupts in
suspend_device_irqs(), including the interrupts marked EARLY_RESUME.
On the resume side things are different. The EARLY_RESUME interrupts
are reenabled in sys_core_ops->resume and the non EARLY_RESUME
interrupts are reenabled in the normal system resume path.
When suspend_noirq() failed or suspend is aborted for any other
reason, we might omit the resume side call to sys_core_ops->resume()
and therefor the interrupts marked EARLY_RESUME are not reenabled and
stay disabled forever.
To solve this, enable all irqs unconditionally in irq_resume()
regardless whether interrupts marked EARLY_RESUMEhave been already
enabled or not.
This might try to reenable already enabled interrupts in the non
failure case, but the only affected platform is XEN and it has been
confirmed that it does not cause any side effects.

If the next seqno returned by the firmware is 0, we return an error
(-16) in the iwl_mvm_get_last_nonqos_seq() function. This is because
we return an integer and don't use any casting when calculating the
last seqno from the one we received. Fix this by using a cast to u16
when doing the calculation, so we return 0xfff0, as we should.

In an open BSS, after suspend/resume, we don't set the last seqno
because the iwl_mvm_setup_connection_keep() returns too early. This
happens because the check to see if we have any keys was returning
immediately, without setting seqno and seqno_valid. Fix this.
