This patch adds support for the Silicon Labs CP2112 "Single-Chip HID USB to
SMBus Master Bridge."
This is a HID device driver which registers as an i2c adapter and gpiochip to
expose these functions of the CP2112. The customizable USB descriptor fields
are exposed as sysfs attributes. The SMBus byte-read, byte-data-read/write,
and word-data-read transfer modes have been tested by talking to an i2c
sensor. The GPIO functions and USB descriptor field programming have also
been tested.

In HID sensor hub, HID physical ids are used to represent different sensors.
For example physical id of 0x73 in usage page = 0x20, represents an
accelerometer. The HID sensor hub driver uses this physical ids to create
platform devices using MFD. There is 1:1 correspondence between an phy id and a
client driver.
But in some cases these physical ids are reused. There is a phy id 0xe1, which
specifies a custom sensor, which can exist multiple times to represent various
custom sensors. In this case there can be multiple instances of client MFD
drivers, processing specific custom sensor. In this case when client driver
looks for report id or a field index, it should still get the report id
specific to its own type. This is also true for reports, they should be
directed towards correct instance. This change introduce a way to parse and
tie physical devices to their correct instance.
Summary of changes:
- To get physical ids, use collections. If a collection of type=physical
exist then use usage id as in the name of platform device name
- As part of the platform data, we assign a hdsev instance, which has
start and end of collection indexes. Using these indexes attributes
can be tied to correct MFD client instances
- When a report is received, call callback with correct hsdev instance.
In this way using its private data stored as part of its registry, it
can distinguish different sensors even when they have same physical and
logical ids.

In some report descriptors, they leave holes in the selectors. In
this case if we use hardcoded selector values, this will result
in invalid values. For example, if there is selectors defined for
Power State from OFF to D0 to D3. We can't use indexes of these states
if some states are not implemented or not present in the report decriptors.
In this case, we need to get the indexes from report descriptors.
One API is added to get the index of a selector. This API will
search for usage id in the field usage list and return the index.

Added STM sensor hub vendor id in HID_SENSOR_HUB_ENUM_QUIRK to
fix report descriptors. These devices uses old FW which uses
logical 0 as minimum. In these, HID reports are not using proper
collection classes. So we need to fix report descriptors,for
such devices. This will not have any impact, if the FW uses
logical 1 as minimum.
We look for usage id for "power and report state", and modify
logical minimum value to 1.
This is a follow-up patch to commit id 875e36f8.

This patch adds runtime PM support for the HID over I2C driver. When the
i2c-hid device is first opened we power it on and on the last close we
power it off. This is actually what the driver is already doing but in
addition it allows subsystems, like ACPI power domain to power off the
device during runtime PM suspend, which should save even more power.
The implementation is not the most power efficient because it needs some
interaction from the userspace (e.g close the device node whenever we are
no more interested in getting events), nevertheless it allows us to save
some power and works with devices that are not wake capable.

Pull ACPI and power management updates from Rafael Wysocki:
"As far as the number of commits goes, the top spot belongs to ACPI
this time with cpufreq in the second position and a handful of PM
core, PNP and cpuidle updates. They are fixes and cleanups mostly, as
usual, with a couple of new features in the mix.
The most visible change is probably that we will create struct
acpi_device objects (visible in sysfs) for all devices represented in
the ACPI tables regardless of their status and there will be a new
sysfs attribute under those objects allowing user space to check that
status via _STA.
Consequently, ACPI device eject or generally hot-removal will not
delete those objects, unless the table containing the corresponding
namespace nodes is unloaded, which is extremely rare. Also ACPI
container hotplug will be handled quite a bit differently and cpufreq
will support CPU boost ("turbo") generically and not only in the
acpi-cpufreq driver.
Specifics:
- ACPI core changes to make it create a struct acpi_device object for
every device represented in the ACPI tables during all namespace
scans regardless of the current status of that device. In
accordance with this, ACPI hotplug operations will not delete those
objects, unless the underlying ACPI tables go away.

This addresses regression caused by commit id "751d17e23a9f7"
iio: hid-sensors: Fix power and report state.
This commit removed a quirk, to change the enumeration base
to 1 from 0 based on an CONFIG paramter. There was objection to
add more changes under this quirk, instead suggested to add an
HID quirk. But there is no easy way to add HID qurik as the
reports are not properly using collection class.
The solution was to use logical minimum, which is a correct way.
There were changes done in firmware to address this.
Unfortunately some devices, still use old FW and can't be upgraded
to newer version on Linux devices as there is no FW upgrade tool
available for Linux devices. So we need to fix report descriptors,
for such devices. This will not have any impact, if the FW uses
logical 1 as minimum.
In this patch we look for usage id for "power and report state", and
modify logical minimum value to 1.
Background on enum:
In the original HID sensor hub firmwares all Named array enums were
to 0-based. But the most recent hub implemented as 1-based,
because of the implementation by one of the major OS vendor.
Using logical minimum for the field as the base of enum. So we add
logical minimum to the selector values before setting those fields.
Some sensor hub FWs already changed logical minimum from 0 to 1
to reflect this and hope every other vendor will follow.
There is no easy way to add a common HID quirk for NAry elements,
even if the standard specifies these field as NAry, the collection
used to describe selectors is still just "logical".

This fix (not very clean though) should fix the long time USB3
issue that was spotted last year. The rational has been given by
Hans de Goede:
----
I think the most likely cause for this is a firmware bug
in the unifying receiver, likely a race condition.
The most prominent difference between having a USB-2 device
plugged into an EHCI (so USB-2 only) port versus an XHCI
port will be inter packet timing. Specifically if you
send packets (ie hid reports) one at a time, then with
the EHCI controller their will be a significant pause
between them, where with XHCI they will be very close
together in time.
The reason for this is the difference in EHCI / XHCI
controller OS <-> driver interfaces.
For non periodic endpoints (control, bulk) the EHCI uses a
circular linked-list of commands in dma-memory, which it
follows to execute commands, if the list is empty, it
will go into an idle state and re-check periodically.
The XHCI uses a ring of commands per endpoint, and if the OS
places anything new on the ring it will do an ioport write,
waking up the XHCI making it send the new packet immediately.
For periodic transfers (isoc, interrupt) the delay between
packets when sending one at a time (rather then queuing them
up) will be even larger, because they need to be inserted into
the EHCI schedule 2 ms in the future so the OS driver can be
sure that the EHCI driver does not try to start executing the
time slot in question before the insertion has completed.
So a possible fix may be to insert a delay between packets
being send to the receiver.

Fix kernel warning and failure to register sensor hub devices with MFD. Now
many devices has in-built sensor hubs. So by default this HID hub, is properly

But if a second sensor hub is attached via USB, which has same sensors, it will
result in kernel warning and failure to register MFD cell as the platform
device sysfs file name will be same as created by in-built sensor hubs. This
patch sets MFD cell id to PLATFORM_DEVID_AUTO. In this way there will never be

2 fixes here.
* The gp2ap020a00f is a simple missing kconfig dependency.
* The hid sensors hub fix is a work around for an issue introduced by hardware
changes due to a certain large software vendor having an 'interesting'
interpretation of the specification and hence indexing some arrays from 1
rather than 0. The fix takes advantage of the logical min and max reading
facilities introduced by the precursor patch to figure out whether we have
a 0 indexed or 1 indexed device and to adjust appropriately. It also
drops a previous kconfig option that allowed this issue to be worked around
at build time.

hid-logitech-dj.c driver needs hidraw to work correctly. Without
hidraw, hid-logitech-dj.c fails during probe() and Logitech
Unifying devices HID reports aren't recognized.
The unifying receiver has 3 usb interfaces. When hid-logitech-dj driver is
loaded, interfaces 0 and 1 are discarded.
Interface 2 consists of a hid class interface with 3 collections, each of
which sports the 'vendor' usage, thus, there is no reason for hid_input to
claim any of them. On the other hand, hidraw has no issue in claiming the
collections, even if they are 'vendor'. As of today, hid-logitech-dj uses
hidraw api to send configuration/control reports to interface 2 of the
Unifying receiver.
Without the hid-logitech-dj driver, interfaces 0 and 1 are claimed by
hid-input, as they correspond to a keyboard and a mouse. But that is not
relevant to the discussion.

When an I2C HID device is powered of during system sleep, as a result of
removing its power resources (by the ACPI core) the interrupt line might go
low as well. This results inadvertent interrupt and wakes the system from
sleep immediately.
To prevent this we disable the device interrupt in the drivers suspend
method and enable it on resume. The device can still wake the system up if
it is wake capable (this also means that not all of its power will be
removed to keep the interrupt line high).

The PS3 Sixaxis controller has 4 LEDs which can be controlled using the same
command as the rumble functionality. It seems not to be possible to only change
the LED without modifying the rumble motor state. Thus both have to be stored
on the host and retransmitted when either the LED or rumble state is changed.
Third party controllers may not support to disable all LEDs at once. These
controllers automatically switch to blinking of all LEDs when no LED is active
anymore.

It is not necessary to keep the LED information in an extra struct which is
only used by the Buzz device. It can also be used by other devices.

More controllers managed by the hid-sony module have 4 LEDs. These can share
most of the functionality provided by the buzz functions.

The commands used to modify the rumble motor state also modifies the LEDs at
the same time. The functionality used to modify this state in the driver has to
be shared between the rumble and LED part. It is therefore better to replace
the "rumble" part of the names with "state".

It looks like this typo was introduced by a mistake in a copy-and-paste in

This reverts commit 86b84167d4 as it introduced a
VID/PID conflict with its original owner: hid-wiimote got
hid:b0005g*v0000054Cp00000306 added but hid-sony already has this id for the
PS3 Remote (and the ID is oficically assigned to Sony).
Revert the commit to avoid hid-sony regression. David is working on a
bluez patch to force proper ID on the wiimote.
