The nyko core controller uses the same output report format as the
sixaxis controllers, but it expects the report id at offset 1.
This does not interfere with the official controllers as this byte
is considered a padding byte by the current code.

This adds rumble and LED support for nyko core controllers
using the sino lite chip vendor:1345 product:3008, for PS3.
Setting operational mode and output reports are the same as
sixaxis but the input report has a different format since the
PS3 accepts HID usb devices. For it to work, an exception is
needed to skip overriding the report descriptor and use the
original one.

When setting the operational mode, some third party (Speedlink Strike-FX)
gamepads refuse the output report. Failing here means we refuse to
initialize the gamepad while this should be harmless.
The weird part is that the initial commit that added this: a7de9b8
("HID: sony: Enable Gasia third-party PS3 controllers") mentions this
very same controller as one requiring this output report.
Anyway, it's broken for one user at least, so let's change it.
We will report an error, but at least the controller should work.
And no, these devices present themselves as legacy Sony controllers
(VID:PID of 054C:0268, as in the official ones) so there are no ways
of discriminating them from the official ones.

Sony has modified the HID descriptor in new revisions of the Dualshock 4 which
causes the size check in the descriptor replacement function to fail. Remove it
so that new revisions of the controller will work correctly.
The module is completely replacing the descriptor instead of patching it, so the
size check isn't really necessary anyways.

On hardware which provides standby power for charging devices the state of the
LEDs and force-feedback on controllers can persist even when the system is in
standby. Additionally, the state of the controllers on resume may be different
from the state they were in at the time when they were suspended (ie. LEDs are
cleared on resume).
This implements the suspend and resume callbacks which saves and clears the
state of the LEDs on suspend and restores them on resume. Force-feedback is
stopped on suspend but not automatically restored on resume until a new event is
received to avoid potentially damaging hardware.
USB Sixaxis and navigation controllers must be reinitialized when the hardware
is reset on resume or they won't send any input reports.

Refactor the output report sending functions to allow for the sending of output
reports without enqueuing a work item. Output reports for any device can now be
sent via the send_output_report function pointer in the sony_sc struct which
points to the appropriate output function. The individual state worker
functions have been replaced with a universal sony_state_worker function which
uses this function pointer.

This commit removes the cap on the DualShock 4 controller reporting rate when
connected using Bluetooth. The previous value of '0xB0' capped the rate to only
20.83 Hz which many userspace utilities mistook as a sign of a bad signal.
Since a 'B' and an '8' can look similar it's possible that someone mistook the
one for another. The new value of '0x80' enables the full 1000 Hz peak
reporting rate that the controller is capable of.
Frank adds: "Back when the original code was written the purpose of that value
was unknown and 0xB0 seemed to work so that's what ended up being used. Now
that we know what it actually does and that 0x80 is a better choice I support
this patch."

When connected via Bluetooth the sixaxis periodically sends reports with an ID
of 1, the second byte 0xff and the rest zeroed. These reports are not related
to the controller state and must be dropped to avoid generating false input
events.

Directly set the initial LED states in the device state struct instead
of copying them from a temporary array.
This allows for the removal of a redundant "x = x" copy loop in
sony_set_leds() that was taking place any time an LED was updated.
It also allows for the simplifying of the parameters in functions dealing
with LED initialization and updates since only a pointer to the sony_sc
struct is needed now.

Change the ownership of power_supply structure from each driver
implementing the class to the power supply core.
The patch changes power_supply_register() function thus all drivers
implementing power supply class are adjusted.
Each driver provides the implementation of power supply. However it
should not be the owner of power supply class instance because it is
exposed by core to other subsystems with power_supply_get_by_name().
These other subsystems have no knowledge when the driver will unregister
the power supply. This leads to several issues when driver is unbound -
mostly because user of power supply accesses freed memory.
Instead let the core own the instance of struct 'power_supply'. Other
users of this power supply will still access valid memory because it
will be freed when device reference count reaches 0. Currently this
means "it will leak" but power_supply_put() call in next patches will
solve it.
This solves invalid memory references in following race condition
scenario:
Thread 1: charger manager
Thread 2: power supply driver, used by charger manager
THREAD 1 (charger manager) THREAD 2 (power supply driver)
========================== ==============================
psy = power_supply_get_by_name()
Driver unbind, .remove
power_supply_unregister()
Device fully removed
psy->get_property()
The 'get_property' call is executed in invalid context because the driver was
unbound and struct 'power_supply' memory was freed.
This could be observed easily with charger manager driver (here compiled
with max17040 fuel gauge):

Add new structure 'power_supply_config' for holding run-time
initialization data like of_node, supplies and private driver data.
The power_supply_register() function is changed so all power supply
drivers need updating.
When registering the power supply this new 'power_supply_config' should be
used instead of directly initializing 'struct power_supply'. This allows
changing the ownership of power_supply structure from driver to the
power supply core in next patches.
When a driver does not use of_node or supplies then it should use NULL
as config. If driver uses of_node or supplies then it should allocate
config on stack and initialize it with proper values.

Replace stack buffers with kernel allocated buffers for sending

Output report buffers are allocated at initialization time to avoid

Fix a few minor issues in the HID descriptor:
- A 6 bit entry had a logical maximum of 255 when the largest it can be is 63.
- A logical max value was incorrectly being set to -1 instead of 255.
- Set the min/max of the gyroscopes to -8192/8191 as that is the range of
values which represent the true controller orientation. Any values beyond
those extents are just noise.

Bit 3 in byte 31 of the Sixaxis report indicates whether the battery is
charging or not charging as opposed to whether or not the cable is plugged in.
As a result, when connected via USB and fully charged, the power_supply status
is wrongly reported as 'Discharging' instead of 'Full'.
Use the battery level value to set the cable state so that the power status
is reported correctly as that seems to be the only reliable way to determine the
cable status on the Sixaxis.
