Input: elantech - fix V4 report decoding for module with middle key

2018-06-22T00:20:11Z

Some touchpad has middle key and it will be indicated in bit 2 of packet[0]. We need to fix V4 formation's byte mask to prevent error decoding. Signed-off-by: KT Liao Cc: stable@vger.kernel.org Signed-off-by: Dmitry Torokhov

Input: elantech - enable middle button of touchpads on ThinkPad P52

2018-06-22T00:19:56Z

PNPID is better way to identify the type of touchpads. Enable middle button support on 2 types of touchpads on Lenovo P52. Cc: stable@vger.kernel.org Signed-off-by: Aaron Ma Reviewed-by: Benjamin Tissoires Signed-off-by: Dmitry Torokhov

Input: psmouse-smbus - allow to control psmouse_deactivate

2018-05-23T23:49:22Z

This seems to be Synaptics specific, as some Elan touchpads are not correctly switching to SMBus if we call deactivate before switching to SMBus on cold boot and on resume. Tested with the T480s Signed-off-by: Benjamin Tissoires Acked-by: KT Liao Signed-off-by: Dmitry Torokhov

Input: elantech - detect new ICs and setup Host Notify for them

2018-05-23T23:49:22Z

New ICs are using a different scheme for the alternate bus parameter. Given that they are new and are only using either PS2 only or PS2 + SMBus Host Notify, we force those new ICs to use the SMBus solution for enhanced reporting. This allows the touchpad found on the Lenovo T480s to report 5 fingers every 8 ms, instead of having a limit of 2 every 8 ms.

Input: elantech - add support for SMBus devices

2018-05-23T23:49:22Z

Many of the Elantech devices are connected through PS/2 and a different bus (SMBus or plain I2C). To not break any existing device, we only enable SMBus based on a module parameter. If some laptops require the quirk to be set, we will have to rely on a list of PNPIds or MDI matching to individually expose those hardware over SMBus. the parameter mentioned above is elantech_smbus from the psmouse module.

Input: elantech - query the resolution in query_info

2018-05-23T23:49:22Z

The command ETP_RESOLUTION_QUERY also contains the bus information. It is better to fetch it once, while we are querying for device information. Signed-off-by: Benjamin Tissoires Acked-by: KT Liao Signed-off-by: Dmitry Torokhov

Input: elantech - split device info into a separate structure

2018-05-23T23:48:49Z

In preparation for SMBus device support, move static device information that we query form the touchpad upon initialization into separate structure. This will allow us to query the device without allocating memory first. Signed-off-by: Benjamin Tissoires Acked-by: KT Liao Signed-off-by: Dmitry Torokhov

Input: psmouse - move sliced command implementation to libps2

2018-02-03T00:50:24Z

In preparation to adding some debugging statements to PS/2 control sequences let's move psmouse_sliced_command() into libps2 and rename it to ps2_sliced_command(). Signed-off-by: Dmitry Torokhov

Input: psmouse - create helper for reporting standard buttons/motion

2018-02-03T00:48:56Z

Many protocol driver re-implement code to parse buttons or motion data from the standard PS/2 protocol. Let's split the parsing into separate functions and reuse them in protocol drivers. Signed-off-by: Dmitry Torokhov

Input: elantech - add new icbody type 15
