[PATCH] HID: add support for PenMount dual-touch panel

[PATCH] HID: add support for PenMount dual-touch panel

[PenMount]

This patch adds PenMount support to hid-multitouch.
A new class MT_CLS_CONFIDENCE_SERIAL_MODE is defined for PenMount,
since it uses HID_DG_CONFIDENCE as the valid flag.
A new quirk MT_QUIRK_SERIAL_REPORT_MODE is defined,
since PenMount uses serial reporting mode and there is no
HID_DG_CONTACTCOUNT usage in it's report descriptor.

Are the events not emitted automatically per touch, if the lines above are omitted?

Benjamin: Since field->index == 0 is in use, it seems the driver could
execute event emission wrongly under some circumstances (when
last_field_index == 0). Is that related to the reason for the quirk in
this patch?

In fact, I have a second patch just on top of this one. It has been
tested by Ryan with PenMount devices.
I was waiting for Penmount to be included first as it does not impact
any other drivers.

I inline the code here, but my gmail client will destroy tabs (so I
attached it too)....

Can you test it against 3M?

Richard, can you test it (after applying the PenMount patch) too?

Thanks,
Benjamin

Subject: [PATCH] HID: hid-multitouch: refactor last_field_index

the current implementation requires the devices to report
HID_DG_CONTACTCOUNT to set the last_field_index value.
However, devices reporting in serial mode (DWAV and PenMount)
do not send this field.
Other devices (3M) add other fields in the reports descriptor
that are not multitouch related at the end, thus the need to
add a special case in the default case when handling events.

A first work around has been set up but with PenMount devices,
we have reached the limit.

The idea is to calculate the last_field_index by relying only on
multitouch fields the device send. This allows us to remove
the handling of non-multitouch events in hid-multitouch, and
guarantee that the function mt_emit_event is always called.

Subject: [PATCH] HID: hid-multitouch: refactor last_field_index

the current implementation requires the devices to report
HID_DG_CONTACTCOUNT to set the last_field_index value.
However, devices reporting in serial mode (DWAV and PenMount)
do not send this field.
Other devices (3M) add other fields in the reports descriptor
that are not multitouch related at the end, thus the need to
add a special case in the default case when handling events.

A first work around has been set up but with PenMount devices,
we have reached the limit.

The idea is to calculate the last_field_index by relying only on
multitouch fields the device send. This allows us to remove
the handling of non-multitouch events in hid-multitouch, and
guarantee that the function mt_emit_event is always called.

Great, and good timing. :-)

I would prefer the opposite order, since it is cleaner and means one
less device to test for the major change.

I will test it against 3M and egalax. Thanks!

I agree with Henrik on this.

Once you are done with testing the last_field_index change, it'd be great 
if you could respin the patches so that the first one perfoms this change, 
and the second one adds PenMount support on top of it.

I'll then apply it. Thanks,

Hi Jiri,

I'll do that as soon as Henrik tells me it is working.

The 3M (0596:0502) and eGalax (0eef:720c) seem to work as expected.

Please just resubmit the patch with modified From: and Signed-off-by: 
lines so that they use real names.

See Documentation/SubmittingPatches, namely chapter 12 for details.

Thanks a lot for your work on supporting the new deivce.

[PATCH] HID: add support for PenMount dual-touch panel

[John Sung]

This patch adds PenMount support to hid-multitouch.
A new class MT_CLS_CONFIDENCE_SERIAL_MODE is defined for PenMount,
since it uses HID_DG_CONFIDENCE as the valid flag.
A new quirk MT_QUIRK_SERIAL_REPORT_MODE is defined,
since PenMount uses serial reporting mode and there is no
HID_DG_CONTACTCOUNT usage in it's report descriptor.

[PATCH] HID: add support for PenMount dual-touch panel

[Benjamin Tissoires]

From: John Sung <penmount.touch@gmail.com>

This patch adds PenMount support to hid-multitouch.
A new class MT_CLS_CONFIDENCE is defined for PenMount,
since it uses HID_DG_CONFIDENCE as the valid flag.

Hi Guys,

this is the final version (I hope so).
I changed the from, restored back the Kconfig part and reintroduced the commit message.
John, I hope it's good for you.

Cheers,
Benjamin

I have modified the commit message slightly, to reflect that Benjamin has 
rebased John's original patch on top of last_index_field changes, and 
applied.
