Hello,

When testing 4.12-rc6 on my HP EliteBook 8570w I noticed the following
in my dmesg output:

[   10.377828] psmouse serio4: synaptics: queried max coordinates: x
[..5648], y [..4806]
[   10.414770] psmouse serio4: synaptics: queried min coordinates: x
[1292..], y [1048..]
[   10.414775] psmouse serio4: synaptics: Your touchpad (PNP: SYN019b
SYN0100 SYN0002 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.
[   10.485294] psmouse serio4: synaptics: Touchpad model: 1, fw: 8.1,
id: 0x1e2b1, caps: 0xd40123/0x840300/0x26c00/0x0, board id: 2009, fw
id: 1119621
[   10.529272] input: SynPS/2 Synaptics TouchPad as
/devices/platform/i8042/serio4/input/input32

So here I am, reporting in. I recompiled 4.12-rc6 with the following
patch, and enabled CONFIG_RMI4_SMB in my kernel config:

After booting the touchpad worked fine, with the following dmesg output.

[   15.852288] psmouse serio4: synaptics: queried max coordinates: x
[..5648], y [..4806]
[   15.891374] psmouse serio4: synaptics: queried min coordinates: x
[1292..], y [1048..]
[   15.891385] psmouse serio4: synaptics: Trying to set up SMBus access
[   15.901853] rmi4_smbus 11-002c: registering SMbus-connected sensor
[   15.938373] rmi4_f01 rmi4-00.fn01: found RMI device, manufacturer:
Synaptics, product: TM2009-001, fw id: 0
[   15.978114] input: Synaptics TM2009-001 as /devices/rmi4-00/input/input33

If you need any more information, I'd be happy to provide it.

Kind regards,

Sibren Vasse
