 All other axes retain their meaning. A device must not mix

-INPUT_PROP_HAPTIC_TOUCHPAD
---------------------------
+INPUT_PROP_PRESSUREPAD
+----------------------
 
-The INPUT_PROP_HAPTIC_TOUCHPAD property indicates that device:
-- supports simple haptic auto and manual triggering
+The INPUT_PROP_PRESSUREPAD property indicates that the device provides
+simulated haptic feedback (e.g. a vibrator motor situated below the surface)
+instead of physical haptic feedback (e.g. a hinge). This property is only set
+if the device:
+
 - can differentiate between at least 5 fingers
 - uses correct resolution for the X/Y (units and value)
-- reports correct force per touch, and correct units for them (newtons or grams)
 - follows the MT protocol type B
 
+If the simulated haptic feedback is controllable by userspace the device must:
+
+- support simple haptic auto and manual triggering, and
+- report correct force per touch, and correct units for them (newtons or grams), and
+- provide the EV_FF FF_HAPTIC force feedback effect.
+
 Summing up, such devices follow the MS spec for input devices in
-Win8 and Win8.1, and in addition support the Simple haptic controller HID table,
-and report correct units for the pressure.
+Win8 and Win8.1, and in addition may support the Simple haptic controller HID
+table, and report correct units for the pressure.
+
+Where applicable, this property is set in addition to INPUT_PROP_BUTTONPAD, it
+does not replace that property.
