2014-08-19Input: drv260x - add TI drv260x haptics driverDan Murphy
Add the TI drv260x haptics/vibrator driver. This device uses the input force feedback to produce a wave form to driver an ERM or LRA actuator device. The initial driver supports the devices real time playback mode. But the device has additional wave patterns in ROM. This functionality will be added in future patchsets.

2014-08-13Input: xpad - add support for Xbox One controllersTed Mielczarek
Xbox One controllers require an initialization message to start sending data, so xpad_init_output becomes a required function. The Xbox One controller does not have LEDs like the Xbox 360 controller, so that functionality is not implemented. The format of messages controlling rumble is currently undocumented, so rumble support is not yet implemented. Note that Xbox One controller advertises three interfaces with the same interface class, subclass and protocol, so we have to also match against interface number.

2014-08-08Input: synaptics - use firmware data for Cr-48Henrik Rydberg
The profile sensor clickpad in a Cr-48 Chromebook does a reasonable job of tracking individual fingers. This tracking isn't perfect, but, experiments show that it works better than just passing "semi-mt" data to userspace, and making userspace try to deduce where the fingers are given a bounding box. This patch tries to report correct two-finger positions instead of the {(min_x, min_y), (max_x, max_y)} for profile sensor clickpads on Cr-48 chromebooks. Note that this device's firmware always reports the higher (smaller y) finger in the "sgm" packet, and the lower (larger y) finger in the "agm" packet. Thus, when a new finger arrives on the pad, the kernel driver uses input core's contact tracking facilities to match contacts with slots.

2014-07-28Input: atmel_mxt_ts - use deep sleep mode when stoppedNick Dyer
By writing zero to both the active and idle cycle times the maXTouch device is put into a deep sleep mode when it consumes minimal power. It is unnecessary to change the configuration of any other objects (for example to disable T9 touchscreen). It is counterproductive to reset the chip on resume, it will result in a long delay. However it is necessary to issue a calibrate command after the chip has spent any time in deep sleep. This patch also deals with the situation where the power configuration is zero on probe, which would mean that the device never wakes up to execute commands.

When there are 2 fingers on the pad we don't know which one is which, so use input_mt_assign_slots to make sure the right set of coordinates ends up in the right slot.
