[PATCH v2 0/3] Support of Perixx Peripad 701 for hid-multitouch

Hi Guys,

This is the v2 of the support of Perixx Peripad 701.

I included the changes asked by Henrik:
- refactor:
+             code = ((usage->hid - 1) & HID_USAGE);
+             code += BTN_MOUSE;
into:
+             code = ((usage->hid - 1) & HID_USAGE) + BTN_MOUSE;

- renamed field maxcontactnumber into maxcontact_report_id
- split the support of the device and the control of the feature Max Contact Number.
- fix typo in commit message

Cheers,
Benjamin
