Input - arizona-haptics: Add driver haptics module on Arizona CODECs
The Arizona CODECs contain a haptics module providing vibration feedback support. Implement basic support for this, providing simple start/stop and signal magnitude control. Since the output path for haptics is routed through the CODEC audio routing it is modelled as a signal generator within ASoC, the haptics driver calls DAPM to start and stop the output drivers. An appropriate output path must be configured via ALSA to connect the haptics source to the correct output. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
