Subject[PATCH v3 3/8] Input: synaptics-rmi4: Add dribble and palm gesture parameters to device tree
Date
Signed-off-by: Andrew Duggan <aduggan@synaptics.com>
---
This version includes Nick's suggestion of adding force to the device tree
parameters so make it obvious that these parameters overwrite the
default values set in the firware config.
