+Dialog Semiconductor DA7280 Haptics bindings
+
+Required properties:
+- compatible: Should be "dlg,da7280".
+- reg: Specifies the I2C slave address.
+
+- interrupt-parent : Specifies the phandle of the interrupt controller to
+  which the IRQs from DA7280 are delivered to.
+- interrupts: IRQ line info for DA7280.
+  (See Documentation/devicetree/bindings/interrupt-controller/
+   interrupts.txt for further information relating to interrupt properties)
+- dlg,vib-mode:
+  "LRA-MODE" - Linear Resonance Actuator mode.
+  "ERM-BAR" - Bar type Eccentric Rotating Mass mode.
+  "ERM-COIN" - Coin type Eccentric Rotating Mass mode.
+- dlg,play-mode: choose one in below five modes.
+  "DRO-MODE" - Direct register override mode.
+  "PWM-MODE" - PWM data source mode.
+	In this case, user is able to set duty to 0 ~ 0xffff(0% ~ 100%)
+  "RTWM-MODE" - Register triggered waveform memory mode.
+	In this case, when enable this mode the pattern assigned
+	to the PS_SEQ_ID will be played as much times as PS_SEQ_LOOP.
+  "ETWM-MODE" - Edge triggered waveform memory mode.
+	In this case, external GPI(N) control are required to enable/disable
+	and it needs to keep device enabled by sending magnitude (X > 0)
+	the pattern assigned to the GPI(N)_SEQUENCE_ID below.
+	For more details, please see the datasheet.
+- dlg,nom-microvolt: Nominal actuator voltage rating.
+- dlg,abs-max-microvolt: Absolute actuator maximum voltage rating.
+- dlg,imax-microamp: Actuator max current rating.
+- dlg,impd-micro-ohms: the impedance of the actuator in micro ohm,
+  as read from its datasheet.
+
+Optional properties:
+- pwms : phandle to the physical PWM(Pulse Width Modulation) device.
+  PWM properties should be named "pwms". And number of cell is different
+  for each pwm device.
+  (See Documentation/devicetree/bindings/pwm/pwm.txt
+   for further information relating to pwm properties)
+- dlg,ps-seq-id: the PS_SEQ_ID(pattern ID in waveform memory inside chip)
+  to play back when RTWM-MODE is enabled.
+- dlg,ps-seq-loop: the PS_SEQ_LOOP, Number of times the pre-stored sequence
+  pointed to	by PS_SEQ_ID or GPI(N)_SEQUENCE_ID is repeated.
+- dlg,gpiN-seq-id: the GPI(N)_SEQUENCE_ID, pattern to play
+  when gpi0 is triggered, 'N' must be 0~2.
+- dlg,gpiN-mode: the pattern mode which can select either
+  "Single-pattern" or "Multi-pattern", 'N' must be 0~2.
+- dlg,gpiN-polarity: gpiN polarity which can be chosen among "Rising-edge",
+  "Falling-edge" and "Both-edge", 'N' must be 0~2.
+  Haptic will work by this edge option in case of ETWM-MODE.
+
+- dlg,resonant-freq-hz: use in case of LRA-MODE, default 205Hz.
+  the freq range: 50Hz ~ 300Hz.
+  It will be set to 205Hz if the value is out of range.
+- dlg,bemf-sens-enable: Enable for internal loop computations.
+- dlg,freq-track-enable: Enable for resonant frequency tracking.
+- dlg,acc-enable: Enable for active acceleration.
+- dlg,rapid-stop-enable: Enable for rapid stop.
+- dlg,amp-pid-enable: Enable for the amplitude PID.
+- dlg,mem-array: use in case that memory registers should be updated,
+  Please fill the whole buffers(100 bytes) to avoid any error in driver.
+  For example,
+	dlg,mem-array = <
+		0x01 0x02 0x03 0x04 0x05 0x06 0x07 0x08 0x09 0x0A
+		...
+		0x71 0x72 0x73 0x74 0x75 0x76 0x77 0x78 0x79 0x7A
+		0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00
+		0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00
+	>;
+
+For further information, see device datasheet.
