Input: synaptics - enable RMI mode for HP Spectre X360

2019-07-25T08:24:06Z

The 2016 kabylake HP Spectre X360 (model number 13-w013dx) works much better with psmouse.synaptics_intertouch=1 kernel parameter, so let's enable RMI4 mode automatically.

Input: elantech - annotate fall-through case in elantech_use_host_notify()

This avoids a warning when building with -Wimplicit-fallthrough. Fixes: 883a2a80f79c ("Input: elantech - enable SMBus on new (2018+) systems") Reported-by: Stephen Rothwell Signed-off-by: Dmitry Torokhov

Input: elantech - enable SMBus on new (2018+) systems

2019-07-23T13:49:22Z

There are some new HP laptops with Elantech touchpad that don't support multitouch. Currently we use ETP_NEW_IC_SMBUS_HOST_NOTIFY() to check if SMBus is supported, but in addition to firmware version, the bus type also informs us whether the IC can support SMBus. To avoid breaking old ICs, we will only enable SMbus support based the bus type on systems manufactured after 2018. Lastly, let's consolidate all checks into elantech_use_host_notify() and use it to determine whether to use PS/2 or SMBus.

Input: alps - fix a mismatch between a condition check and its comment

2019-07-19T09:40:35Z

In the function alps_is_cs19_trackpoint(), we check if the param[1] is in the 0x20~0x2f range, but the code we wrote for this checking is not correct: (param[1] & 0x20) does not mean param[1] is in the range of 0x20~0x2f, it also means the param[1] is in the range of 0x30~0x3f, 0x60~0x6f... Now fix it with a new condition checking ((param[1] & 0xf0) == 0x20).

Input: alps - don't handle ALPS cs19 trackpoint-only device

2019-07-15T17:19:08Z

On a latest Lenovo laptop, the trackpoint and 3 buttons below it don't work at all, when we move the trackpoint or press those 3 buttons, the kernel will print out: "Rejected trackstick packet from non DualPoint device" This device is identified as an alps touchpad but the packet has trackpoint format, so the alps.c drops the packet and prints out the message above. According to XiaoXiao's explanation, this device is named cs19 and is trackpoint-only device, its firmware is only for trackpoint, it is independent of touchpad and is a device completely different from DualPoint ones. To drive this device with mininal changes to the existing driver, we just let the alps driver not handle this device, then the trackpoint.c will be the driver of this device if the trackpoint driver is enabled. (if not, this device will fallback to a bare PS/2 device) With the trackpoint.c, this trackpoint and 3 buttons all work well, they have all features that the trackpoint should have, like scrolling-screen, drag-and-drop and frame-selection.

Input: synaptics - whitelist Lenovo T580 SMBus intertouch

Adds the Lenovo T580 to the SMBus intertouch list for Synaptics touchpads. I've tested with this for a week now, and it seems a great improvement. It's also nice to have the complaint gone from dmesg. Signed-off-by: Nick Black Cc: stable@vger.kernel.org Signed-off-by: Dmitry Torokhov
