I'll fix this, I'll take the cover letter as commit message and update
the mail address.

Do you want me to also change the atmel_ptc.h header and use __u8 and co?
Since I share it with bare metal software, uintxx_t was more convenient.

Tooling and examples are in development.
The tool allows you to produce the atmel_ptc.conf binary or to tweak the
configuration in real time with commands such as:
- set node_group_conf count 10
- get node_config 0
- dump_conf
- export_conf atmel_ptc.conf
The application only use input devices.
