+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.
