Todd Kelner b7289cb1cf HID: sony: Add touchpad support for NSG-MR5U and NSG-MR7U remotes
Sony's NSG-MR5U and NSG-MR7U remote controls have a full keyboard and a
touchpad.  The keyboard is already supported by the existing Linux
kernel and drivers but the touchpad is not recognized.  This patch adds
the coded needed to bring full functionality to the touchpad.

Note that these remotes use the vendor code for SMK even though they are
Sony branded.

Known limitations
- The built-in accelerometers are not supported by these changes
- When the Drag (Fn) key is used as a mouse button, the button is
automatically released when the key begins repeating.  There are two
  workarounds for this 1) Use the button behind the touchpad instead of
  the Drag (Fn) key or 2) Disable the key repeat functionality or
  increase the key repeat delay.

Roderick Colenbrander 77b499e739 HID: sony: Make DS4 bt poll interval adjustable
By default when using bluetooth the DS4 reports data at about 1kHz,
which is quite fast especially on weak devices. We now make the
device use the USB poll interval, which is a fixed 4ms. In addition
we make the value adjustable through sysfs.

The error handling in sony_input_configured is a little tricky. It
is not easy to add other goto's as not all codepaths have logic
for adding this attribute. Luckily we are setting the value for the
attribute to a default value, so we can use that to detect if we need
to remove the file.

Roderick Colenbrander e19a267b99 HID: sony: DS3 comply to Linux gamepad spec
The axis and button mapping for the DS3 is strange. This is mostly
due to the device reporting many axes as for every digital button
it also has an analog button. Due to amount of analog values it
is even leaking well into the MT axes range.

We felt it is best to remove the many analog buttons and just report
digital and comply to the Linux gamepad spec. The analog buttons are
rarely used on the official platform, let alone on Linux.

This patch does remove motion sensor support (added back in another
patch).

Roderick Colenbrander d03ae2e108 HID: sony: Remove report descriptor fixup for DS4
The DS4 in BT mode sends initial input reports through report 1, which
is described in the HID report descriptors. When activated after sending
a certain feature report, the device uses report 17.

Currently the hid-sony driver fixes up the BT HID report descriptors,
so the HID layer can manage input reports for report 17.

We think it is best to eliminate this fixup and do the handling ourselves,
which is what this patch does. The main motivation is that there are
various users of DS4 through hidraw, including various cross-platform
applications/games, which have their own HID parsing across Linux/Win/OSX.
Due to the fixup the descriptors differ, which is causing pain for many
developers including major game publishers (who reached out privately).
Without the fixup, the Windows titles also have a fighting chance for
working on Wine, which provides HID support now. Overall it felt
best because of these reasons to remove the fixup.

The DS4 motion sensors require calibration for accurate operation.

Roderick Colenbrander 227c011b2e HID: sony: Report DS4 motion sensors through a separate device
The DS4 motion sensors are currently mapped by the hid-core driver
to non-existing axes in between ABS_MISC and ABS_MT_SLOT, because
the device already exhausted ABS_X-ABS_RZ. For a part the mapping
by hid-core is accomplished by a fixup in hid-sony as the motion
axes actually use vendor specific usage pages.

This patch makes the DS4 use a separate input device for the motion
sensors and reports acceleration data through ABS_X-ABS_Z and
gyroscope data through ABS_RX-ABS_RZ. In addition it extends the
event spec to allow gyroscope data through ABS_RX-ABS_RZ when
INPUT_PROP_ACCELEROMETER is set. This change was suggested by
Peter Hutterer during a discussion on linux-input.

When a user connects a DS4 twice using USB and BT, we reject the

Roderick Colenbrander 9131f8cc2b HID: sony: Comply to Linux gamepad spec for DS4

and axes based on the HID report descriptors. The default mapping
was strange e.g. right stick using ABS_Z/ABS_RZ or the physical
'south button' being reported as BTN_EAST etcetera.

This patch makes the DS4 side ofi the hid-sony driver comply to

Dmitry on the linux-input list.

Currently the main user of the DS4 is the SDL2 library, which has
a mapping table using vendor/device/version as a key. In order to
not break SDL2 we discussed adjusting the version number, so it
can have both mappings. This was discust on linux-input and we

Roderick Colenbrander ac797b95f5 HID: sony: Make the DS4 touchpad a separate device
The dualshock 4 supports both analog sticks of which one uses
ABS_X/_Y and a touchpad. In a recent discussion with Dmitry about
some input-mt changes we proposed for disabling pointer emulation from
input_mt_sync_frame, Dmitry mentioned ABS_X/_Y should report the
same data as ABS_MT_POSITION_X/_Y. The current driver is mixing axes
for different subdevices. It was suggested to make the touchpad
its own sub-device.

This patch turns the touchpad into its own device. In addition
this patch also moves the button underneath the touchpad into
the new device. It felt like this button should be part of the
device. No known user space application (not even SDL2) seems to
be using it.

as hid_hw_start doesn't fail. As was discussed on linux-input, it is
acceptable for this function to fail.

to determine whether initialization succeeded correctly. The flag is

Roderick Colenbrander 2c159de050 HID: sony: Adjust HID report size name definitions
Put the report type (feature / output) in the report size definitions.
This prevents name collisions later on for other different reports, which use
the same report id, but have a different size.

Roderick Colenbrander e1bc84d007 HID: sony: Fix race condition in sony_probe
Early on the sony_probe function calls hid_hw_start to start the hardware.
Afterwards it issues some hardware requests, initializes other functionality
like Force Feedback, power classes and others. However by the time
hid_hw_start returns, the device nodes have already been created, which leads
to a race condition by user space applications which may detect the device
prior to completion of initialization. We have observed this problem many
times, this patch fixes the problem.

This patch moves most of sony_probe to sony_input_configured, which is called
prior to device registration. This fixes the race condition and the same
approach is used in other HID drivers.

Frank Praznik c4425c8f26 HID: sony: Update copyright and add Dualshock 4 rate control note
Update the copyright notice with the current year and add a note
about values for controlling the Dualshock 4 reporting rate.

Processing reports at the default full rate of 1000hz can be too
demanding for some low-power embedded processors so noting
alternate values for people working with this hardware can be useful.

Thanks to Rostislav Pehlivanov for finding these values.

Frank Praznik 2a24293277 HID: sony: Defer the initial USB Sixaxis output report
When initially connected via USB the Sixaxis isn't fully initialized
until the PS logo button is pressed and won't send any input reports
nor will any state set by output reports be retained.

This adds a 'defer_initialization' flag to the sony_sc struct which,
when set, will delay sending any output reports until the first input
report has arrived. This flag is used with the USB Sixaxis to ensure
that any state sent will persist since, until the PS button is pushed,
any changes sent to the controller via an output report will be lost
after a couple of seconds.

The initial state of the controller is still configured at the time
of the initial connection and won't be internally modified after that,
so any state set by the user between that time and the recepit of the
first input report won't be lost.

Frank Praznik 0f3982308b HID: sony: Relax duplicate checking for USB-only devices
Some USB-only devices which masquerade as Sixaxis controllers report the
same generic Bluetooth address for all hardware when queried via the HID
report. This causes these devices to be wrongly rejected as duplicates
when more than one is connected at once.

This introduces a connection type comparison when checking for duplicates
and only rejects the newly connected device if the existing matching
device is connected using a different connection protocol.

The results of the connection type comparison are also used when
registering power supply info as the device Bluetooth address is used
as the unique identifier string.  In cases where more than one valid
device has the same Bluetooth address the device ID is now appended
to the power supply name string to avoid name collisions when
registering the power supply information.
