+description: |
+ Qualcomm SPMI haptics is a peripheral on some QTI PMICs. It supports linear resonant
+ actuators and eccentric rotating mass type haptics commonly found in mobile devices.
+ It supports multiple sources of wave data such as an internal buffer, direct play
+ (from kernel or userspace) as well as an audio output mode.
