iio: ltr501: Add interrupt rate control support
Added rate control support for ALS and proximity
threshold interrupts.Also, Added support to modify

LTR-501 supports interrupt rate control using persistence
register settings. Writing <n> to persistence register
would generate interrupt only if there are <n> consecutive
data values outside the threshold range.
Since we don't have any existing ABI's to directly
control the persistence register count, we have implemented
the rate control using IIO_EV_INFO_PERIOD. _period event
attribute represents the amount of time in seconds an
event should be true for the device to generate the
interrupt. So using _period value and device frequency,
persistence count is calculated in driver using following
logic.
count = period / measurement_rate
If the given period is not a multiple of measurement rate then
we round up the value to next multiple.
This patch also handles change to persistence count whenever
there is change in frequency.

iio: sx9500: optimize power usage
In the interest of lowering power usage, we only activate the proximity
channels and interrupts that we are currently using.
For raw reads, we activate the corresponding channel and the data ready
interrupt and wait for the interrupt to trigger. If no interrupt is
available, we wait for the documented scan period, as specified in the
datasheet.
The following types of usage patterns may overlap:
* raw proximity reads (need a single data ready interrupt)
* trigger usage (needs data ready interrupts as long as active)
* proximity events (need near/far interrupts)
* triggered buffer reads (don't need any interrupts, but are usually
coupled with our own trigger.
To mitigate all possible patterns, we implement usage counting for all
the resources used: data ready interrupts, near/far interrupts and
individual channels.
The device enters sleep mode as documented in the data sheet when its
buffer, trigger and events are disabled, and no raw reads are currently
running.
Because of this new usage pattern, it is important that we give the
device a chance to perform an initial compensation for all its channels
at probe time.

However, dsa_of_setup_routing_table() fills 'rtable' with port numbers

This commit removes redundant devicetree parsing and adds needed port

looks for target switch number by parsing parent of 'link' device node.
To remove possible misunderstandings with the way of determining target

This was tested on a custom board with two Marvell 88E6095 switches with

netns: don't allocate an id for dead netns
First, let's explain the problem.
Suppose you have an ipip interface that stands in the netns foo and its link
part in the netns bar (so the netns bar has an nsid into the netns foo).
Now, you remove the netns bar:
- the bar nsid into the netns foo is removed
- the netns exit method of ipip is called, thus our ipip iface is removed:
=> a netlink message is built in the netns foo to advertise this deletion
=> this netlink message requests an nsid for bar, thus a new nsid is
allocated for bar and never removed.
This patch adds a check in peernet2id() so that an id cannot be allocated for
a netns which is currently destroyed.

staging: fsl-mc: Changed version matching rules for MC object drivers
Before this change, we were requiring a complete version match (major and
minor version numbers) between MC objects and corresponding drivers, to
allow MC objects to be bound to their drivers. We realized that a mismatch
in minor version numbers should be tolerated, as long as the major version
numbers match. This allows the driver to decide what to do in the minor
version mismatch case. For example, a driver may decide to run with
downgraded functionality if the MC firmware object has older minor version
number than the driver. Also, a driver with older minor version than the
MC firmware object may decide to run even though it cannot use newer
functionality of the MC object.
As part of this change, the dpmng Flib version was also updated
to match the latest MC firmware version.

staging: fsl-mc: Refactored fsl_mc_object_allocator driver init/exit
The fsl_mc_allocator driver does not need to be its own module
as it is tightly integrated into the MC bus main driver. It is really
just a sub-component of the MC bus driver. By not making fsl_mc_allocator
its own module, we can have more control of when its initialization happens
and we want it to happen before any driver that depends on the MC bus
driver gets initialized.

MC objects discovered during an MC bus scan were being reordered
