2017-05-30Input: 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.

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.

2017-05-23Input: 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.

2017-04-14Input: ar1021_i2c - fix too long name in driver's device tableDmitry Torokhov1-1/+1
The name field in structure i2c_device_id is 20 characters, and we expect it to be NULL-terminated, however we are trying to stuff it with 21 bytes and thus NULL-terminator is lost. This causes issues when one creates device with name "MICROCHIP_AR1021_I2C" as i2c core cuts off the last "C", and automatic module loading by alias does not work as result. The -I2C suffix in the device name is superfluous, we know what bus we are dealing with, so let's drop it. Also, no other driver uses capitals, and the manufacturer name is normally not included, except in very rare cases of incompatible name collisions.

There are several quirky Xbox One pads that depend on initialization packets that the Microsoft pads don't require. To deal with these, I've added a mechanism for issuing device-specific initialization packets using a VID/PID-based quirks list.

This should enable full functionality on the following quirky pads: 0x0e6f:0x0165 - Titanfall 2 gamepad (previously fully non-functional) 0x0f0d:0x0067 - Hori Horipad (analog sticks previously non-functional) 0x24c6:0x541a - PowerA Xbox One pad (previously fully non-functional) 0x24c6:0x542a - PowerA Xbox One pad (previously fully non-functional) 0x24c6:0x543a - PowerA Xbox One pad (previously fully non-functional) [0]: https://github.com/ValveSoftware/steamlink-sdk/blob/master/kernel/drivers/input/joystick/xpad.c [1]: https://github.com/360Controller/360Controller Signed-off-by: Cameron Gutman <aicommander@gmail.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
