This patch adds support for the GPIO keyboard used on MX6Q SabreLite.
This is generally used for invoking Android "recovery mode" in
response to a long press of volume key down during boot.
This can be tested by a boot script like so:
if keypress voldown&& sleep 1&& keypress voldown ; then
echo "do recovery thing" ;
fi
Key values can be seen by issuing keypress with no arguments:
I don't like introducing yet another way to handle key presses and
create menu like interfaces from this.
We already have two of these:
- We have the powerful and flexible method to map key preesses to
envrionment variables which can in turn hold commands (variables
"magic_keys" and "key_magic*") as used for example on the enbw_cmc,
lwmon5, hmi1001, mucmc52, pcs440ep, r360mpi and mucmc52 boards.
- We have the menu system as implemented by common/menu.c etc.
Please use either of these, but don't invent a new one. Thanks.
Thanks for the pointers. I'll rework accordingly.
Grepping the sources rarely results in this kind of insight.
Regards,
Eric
