Introduce data structures and code allowing "built-in" properties
to be associated with devices in such a way that they will be used
by the device_property_* API if no proper firmware node (neither DT
nor ACPI) is present for the given device.
Each property is to be represented by a property_entry structure.
An array of property_entry structures (terminated with a null
entry) can be pointed to by the properties field of struct
property_set that can be added as a firmware node to a struct
device using device_add_property_set(). That will cause the
device_property_* API to use that property_set as the source
of properties if the given device does not have a DT node or
an ACPI companion device object associated with it.

Add a secondary pointer to struct fwnode_handle so as to make it
possible for a device to have two firmware nodes associated with
it at the same time, for example, an ACPI node and a node with
a set of properties provided by platform initialization code.
In the future that will allow device property lookup to fall back
from the primary firmware node to the secondary one if the given
property is not present there to make it easier to provide defaults
for device properties used by device drivers.
Introduce two helper routines, set_primary_fwnode() and
set_secondary_fwnode() allowing callers to add a primary/secondary
firmware node to the given device in such a way that
(1) If there's only one firmware node for that device, it will be
pointed to by the device's firmware node pointer.
(2) If both the primary and secondary firmware nodes are present,
the primary one will be pointed to by the device's firmware
node pointer, while the secondary one will be pointed to by the
primary node's secondary pointer.
(3) If one of these nodes is removed (by calling one of the new
nelpers with NULL as the second argument), the other one will
be preserved.
Make ACPI use set_primary_fwnode() for attaching its firmware nodes
to devices.

With this patch kernel will be able to handle setup request. This is
needed if we would like to handle control mesages with extension
headers. User space will be only resposible for reading setup data and
checking if scenario is conformance to specification (dst and src device
bnep role). In case of new user space, setup data must be leaved(peek
msg) on queue. New bnep session will be responsible for handling this
data.

Handling extended headers of control frames is required BNEP
functionality. This patch refractor bnep rx frame handling function.
Extended header for control frames shouldn't be omitted as it was
previously done. Every control frame should be checked if it contains
extended header and then every extension should be parsed separately.

This is needed if user space wants to know supported bnep features
by kernel, e.g. if kernel supports sending response to bnep setup
control message. By now there is no possibility to know supported
features by kernel in case of bnep. Ioctls allows only to add connection,
delete connection, get connection list, get connection info. Adding
connection if it's possible (establishing network device connection) is
equivalent to starting bnep session. Bnep session handles data queue of
transmit, receive messages over bnep channel. It means that if we add
connection the received/transmitted data will be parsed immediately. In
case of get bnep features we want to know before session start, if we
should leave setup data on socket queue and let kernel to handle with it,
or in case of no setup handling support, if we should pull this message
and handle setup response within user space.

Document cpuidle states of QCOM cpus. In addition to arm-idle-state
compatible string, the ARM idle state definition must define one of the
following compatible strings -
"qcom,idle-state-ret",
"qcom,idle-state-spc",
"qcom,idle-state-pc",
The compatibles helps the SPM platform driver to use the correct idle
function when the index to the idle state is passed to the platform
driver.

- Add device-tree support to the wlcore (wl12xx/wl18xx) driver.
- Update the current users to use the bindings instead of pdata-quirks.
- Finally, remove the deprecated wl12xx_platform_data struct
Note that da850 board file code that still uses the platform data,
but we have da850.dtsi that can be used instead. So it was decided
that we should try to remove the wl12xx support from the da850
board file as suggested by Sekhar Nori <nsekhar@ti.com>. As it's
the last patch in the series, the last patch can be simply reverted
if needed.
As this series touches quite a bit of arch code, it was suggested
by Kalle Valo <kvalo@codeaurora.org> that the whole series should
be merged via the arm-soc tree.

Probe deferral is not an error case. It happens only when
the necessary dependencies are not there yet.
The driver core is already printing a message when a driver
requests probe deferral, so this can be traced in the logs
without these error prints.

All backends are reimplementing a variation of the same CPU reference
count handling. They are also responsible for driving the MCPM special
low-level locking. This is needless duplication, involving algorithmic
requirements that are not necessarily obvious to the uninitiated.
And from past code review experience, those were all initially
implemented badly.
After 3 years, it is time to refactor as much common code to the core
MCPM facility to make the backends as simple as possible. To avoid a
flag day, the new scheme is introduced in parallel to the existing
backend interface. When all backends are converted over, the
compatibility interface could be removed.
The new MCPM backend interface implements simpler methods addressing
very platform specific tasks performed under lock protection while
keeping the algorithmic complexity and race avoidance local to the
core code.
