2017-05-29Input: synaptics - keep PS/2 around when RMI4_SMB is not enabledBenjamin Tissoires1-1/+2
Or the user might have the touchpad unbound from PS/2 but never picked up by rmi-smbus.ko Signed-off-by: Benjamin Tissoires <benjamin.tissoires@redhat.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2017-05-29Input: synaptics - clear device info before filling inEric Biggers1-0/+2
synaptics_query_hardware() was being passed a 'struct synaptics_device_info' in uninitialized stack memory, then not always initializing all fields. This caused garbage to show up in certain fields, making the touchpad unusable. Fix by zeroing the device info, so all fields default to 0.

2017-05-29Input: silead - disable interrupt during suspendHans de Goede1-0/+3
When we put the touchscreen controller in low-power mode the irq pin may trigger (float) and if we then try to read a data packet we get the following error in dmesg: [ 478.801017] silead_ts i2c-MSSL1680:00: Data read error -121 This commit disables the irq during suspend/resume fixing this error.

2017-05-25Input: elan_i2c - ignore signals when finishing updating firmwareKT Liao1-13/+8
Use wait_for_completion_timeout() instead of wait_for_completion_interruptible_timeout() to avoid stray signals ruining firmware update. Our timeout is only 300 msec so we are fine simply letting it expire in case device misbehaves. Signed-off-by: KT Liao <kt.liao@emc.com.tw> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2017-05-25Input: elan_i2c - clear INT before resetting controllerKT Liao1-1/+8
Some old touchpad FWs need to have interrupt cleared before issuing reset command after updating firmware. We clear interrupt by attempting to read full report from the controller, and discarding any data read.

2017-05-22Input: edt-ft5x06 - increase allowed data range for threshold parameterMartin Kepplinger3-3/+3
The datasheet and application note does not mention an allowed range for the M09_REGISTER_THRESHOLD parameter. One of our customers needs to set lower values than 20 and they seem to work just fine on EDT EP0xx0M09 with T5x06 touch. So, lacking a known lower limit, we increase the range for thresholds, and set the lower limit to 0. The documentation is updated accordingly.

2017-05-07Input: xpad - sync supported devices with xboxdrvBenjamin Valentin1-0/+13
The userspace xboxdrv driver [0] contains some USB IDs unknown to the kernel driver. I have created a simple script [1] to extract the missing devices and add them to xpad. A quick google search confirmed that all the new devices called Fightstick/pad are Arcade-type devices [2] where the MAP_TRIGGERS_TO_BUTTONS option should apply. There are some similar devices in the existing device table where this flag is not set, but I did refrain from changing those.
