Instead of open-coded reporting number of fingers on the touchpad
let's use input_mt_report_finger_count() helper.

This patch adds semi-MT support for ALPS v4 protocol touchpads.
It is based on the work by Seth Forshee for ALPS v3 and v4 protocol
support. Three packets are required to assemble and process the MT
data. ST events are reported at once to avoid latency. If there
were two contacts or more, report MT data instead of ST events.
Thanks to Seth Forshee for providing most of the code, guidance
and insight for producing this patch.

This driver adds support for the Synaptics NavPoint touchpad connected
to a PXA27x SSP port in SPI slave mode. The device emulates a mouse;
a tap or tap-and-a-half drag gesture emulates the left mouse button.
For example, use the xf86-input-evdev driver for an X pointing device.

atmel_mxt devices will send a checksum byte at the end of a message if
the MSB of the object address is set.
However, since this driver does not set this bit, the checksum byte
isn't actually sent, so don't even try to read it.

Hardware since Cx supports an unique identity (used to identify OEM vendors
and released lot number) which is very helpful for diagnostic purpose.
This revision tries to make it as a part of driver boot up message.
Whilst here, also bumping fsp_drv_ver to acknowledge recent addition of

Previously I had made the struct device point to the input device, but
after talking with Dmitry, he said that the USB device would make more
sense for this driver to point to. So converted it to use that instead.

According to the standard count 0 is special - no IO should happen but we
can check error conditions (device gone away, etc), and return 0 if there
are no errors. We used to return -EINVAL instead and we also could return 0
if an event was "stolen" by another thread.

When copy_to/from_user fails in the middle of transfer we should not
report to the user that read/write partially succeeded but rather
report -EFAULT right away, so that application will know that it got
its buffers all wrong.
If application messed up its buffers we can't trust the data fetched
from userspace and successfully written to the device or if data read
from the device and transferred to userspace ended up where application
expected it to end.
If serio_write() fails we still going to report partial writes if failure
happens in the middle of the transfer.
This is basically a revert of 7a0a27d2ce38aee19a31fee8c12095f586eed393
and 4fa0771138d0b56fe59ab8ab3b1ce9e594484362.
