+ which the IRQs from DA7280 are delivered to.
+
+- dlg,actuator-type: Set Actuator type. it should be one of:
+ "LRA" - Linear Resonance Actuator type.
+ "ERM-bar" - Bar type Eccentric Rotating Mass.
+ "ERM-coin" - Coin type Eccentric Rotating Mass.

+ assigned to the PS_SEQ_ID played as much times as PS_SEQ_LOOP,
+ 2 - Edge triggered waveform memory(ETWM) mode, external GPI(N)
+ control are required to enable/disable and it needs to keep
+ device enabled by sending magnitude (X > 0),
+ the pattern is assigned to the GPI(N)_SEQUENCE_ID below.
+ The default value is 1 for both of the operation modes.
+ For more details, please see the datasheet.
