HID: sony: Add force feedback support for Dualshock3 USB
Sony Dualshock 3 controllers have two motors which can be used to provide simple force feedback rumble effects. The right motor is can be used to create a weak rumble effect but does not allow to set the force. The left motor is used to create a strong rumble effect with adjustable intensity. The state of both motors can be changed using HID_OUTPUT_REPORT packets and have no timing information. FF memless is used to keep track of the timing and the sony driver just generates the necessary URBs. Signed-off-by: Sven Eckelmann <sven@narfation.org> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
