Subject: [PATCH] hwdb: 60-keyboard: Fix volume-button mapping on Asus TF103C
|
|
|
8d419f |
|
|
|
8d419f |
The Asus TF103C misses the home button in its PNP0C40 GPIO resources
|
|
|
8d419f |
causing the button mappings for the volume buttons to be off by one,
|
|
|
8d419f |
leading to the volume-up button sending home button presses and the
|
|
|
8d419f |
volume-down button sending volume-up button presses.
|
|
|
8d419f |
|
|
|
8d419f |
Add a 60-keyboard hwdb entry to correct the mappings. Note this is
|
|
|
8d419f |
split over 2 input devices because the soc_button_array driver
|
|
|
8d419f |
creates separate input devices for power + home and vol up/down.
|
|
|
8d419f |
This is done because power/home act as wakeup buttons where as
|
|
|
8d419f |
the volume buttons do not.
|
|
|
8d419f |
|
|
|
8d419f |
This means that after this fixup the home -> volume-up button
|
|
|
8d419f |
still acts as a wakeup button, there is nothing which can be done
|
|
|
8d419f |
about this without adding a kludge to the kernel which is not
|
|
|
8d419f |
worth the trouble (IMHO).
