Revert "Input: synaptics - enable RMI mode for X1 Extreme 2nd Generation"

2019-11-22T23:19:03Z

This reverts commit 68b9c5066e39af41d3448abfc887c77ce22dd64d. Ugh, I really dropped the ball on this one :\. So as it turns out RMI4 works perfectly fine on the X1 Extreme Gen 2 except for one thing I didn't notice because I usually use the trackpoint: clicking with the touchpad. Somehow this is broken, in fact we don't even seem to indicate BTN_LEFT as a valid event type for the RMI4 touchpad. And, I don't even see any RMI4 events coming from the touchpad when I press down on it. This only seems to work for PS/2 mode. Since that means we have a regression, and PS/2 mode seems to work fine for the time being - revert this for now. We'll have to do a more thorough investigation on this.

Input: synaptics - enable RMI mode for X1 Extreme 2nd Generation

2019-11-15T22:57:59Z

Just got one of these for debugging some unrelated issues, and noticed that Lenovo seems to have gone back to using RMI4 over smbus with Synaptics touchpads on some of their new systems, particularly this one. So, let's enable RMI mode for the X1 Extreme 2nd Generation. Signed-off-by: Lyude Paul Link: https://lore.kernel.org/r/20191115221814.31903-1-lyude@redhat.com Signed-off-by: Dmitry Torokhov

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: synaptics - whitelist Lenovo T580 SMBus intertouch

2019-07-12T06:56:01Z

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

Input: synaptics - enable SMBUS on T480 thinkpad trackpad

2019-07-01T08:22:21Z

Thinkpad t480 laptops had some touchpad features disabled, resulting in the loss of pinch to activities in GNOME, on wayland, and other touch gestures being slower. This patch adds the touchpad of the t480 to the smbus_pnp_ids whitelist to enable the extra features. In my testing this does not break suspend (on fedora, with wayland, and GNOME, using the rc-6 kernel), while also fixing the feature on a T480.
