While debugging poor gesture (swipes etc.) performance for my touchpad I found this message in the boot log:
> smouse serio1: synaptics: Your touchpad (PNP: LEN007a PNP0f13) says it can support a different bus. If i2c-hid and hid-rmi are not used, you might want to try setting psmouse.synaptics_intertouch to 1 and report this to linux-input@vger.kernel.org.
After setting psmouse.synaptics_intertouch=1 and rebooting the following appears:
> kernel: rmi4_f01 rmi4-00.fn01: found RMI device, manufacturer: Synaptics, product: TM3145-006, fw id: 2491763
> kernel: input: Synaptics TM3145-006 as /devices/rmi4-00/input/input17
> kernel: serio: RMI4 PS/2 pass-through port at rmi4-00.fn03
and gestures works much better :)
I have not experienced issues with suspend etc. yet. (tested for a couple weeks)
