Temporary got a Fujitsu Lifebook E547 into my hands and noticed
the touchpad only works after running
echo "1" > /sys/devices/platform/i8042/serio2/crc_enabled
Add it to the list of Fujitsu machines that need this workaround.

Thanks !
Reviewed-by: Ulrik De Bie <ulrik.debie-os@e2big.org>
Can you also provide the line equivalent for
* Fujitsu LIFEBOOK E554 0x570f01 40, 14, 0c 2 hw buttons
?
Kind regards,
Ulrik

Where do I find those three values mentioned in the third column? And is
that line important at all? I just did below patch as a drive-by-patch
and from looking at the source code I can't immediately spot how to get
them :-/
FWIW, it's a 2 hw buttons touchpad and I saw this in dmesg
psmouse serio2: elantech: assuming hardware version 4 (with firmware
version )
psmouse serio2: elantech: Synaptics capabilities query result 0x50,
0x12, 0x09.
psmouse serio2: elantech: Elan sample query result 01, 27, 86
Are those values from "Elan sample query result" what you are looking
for? Then the line would be:
Fujitsu LIFEBOOK E547 0x470f00 01, 27, 86 2 hw buttons
Ciao, Thorsten

Lo! Dmitry, did this fall through the cracks or is there any reason why
you didn't yet apply below patch? If the latter: What is needed to get
things moving? Right now I still have access to the machine for further
tests, but that will change in a week or two. Ciao, Thorsten

I was waiting for an updated version of the patch with updated info for
E547. The "caps" data is coming from Synaptics caps query, so should be
"50, 12, 09".
Thanks.

/me opens eyes properly and reads the output from dmesg again
/me wonders why he hadn't noticed the capabilities output from the
synaptics driver before and missed the obvious connection
Many thx for the pointer! Find an updated patch below.
