      HID: sony: Comply to Linux gamepad spec for DS4 · 9131f8cc
      由 Roderick Colenbrander 提交于 
      The DS4 side of hid-sony used the hid-core layer to assign buttons
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
the Linux game controller spec as suggested in a discussion with
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
discussed privately with SDL2 developers.

      HID: sony: Make the DS4 touchpad a separate device · ac797b95
      由 Roderick Colenbrander 提交于 
      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.

      HID: sony: Fix memory issue when connecting device using both Bluetooth and USB · 4f967f6d
      由 Roderick Colenbrander 提交于 
      A previous patch moved most input initialization from sony_probe to
sony_input_configured to avoid some race conditions. The driver has some
special logic to prevent the device to get registered twice in case the
user connects it both over Bluetooth and USB. When this condition
happens sony_input_configured returns a failure, but sony_probe continues
as hid_hw_start doesn't fail. As was discussed on linux-input, it is
acceptable for this function to fail.

This patch adds a check for the HID_CLAIMED_INPUT flag within sony_probe
to determine whether initialization succeeded correctly. The flag is
not set by the HID layer when sony_input_configured fails.

      HID: sony: Update copyright and add Dualshock 4 rate control note · c4425c8f
      由 Frank Praznik 提交于 
      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.

      HID: sony: Defer the initial USB Sixaxis output report · 2a242932
      由 Frank Praznik 提交于 
      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.

      HID: sony: Relax duplicate checking for USB-only devices · 0f398230
      由 Frank Praznik 提交于 
      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.
