Convert the Dialog Semiconductor DA7280 Low Power High-Definition
Haptic Driver bindings to dt-schema.
Due to the implementation and usage in DT the array must be
an uint32 array.

-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.
-
-- 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.
-
-- dlg,const-op-mode: Haptic operation mode for FF_CONSTANT.
- Possible values:
- 1 - Direct register override(DRO) mode triggered by i2c(default),
- 2 - PWM data source mode controlled by PWM duty,
-- dlg,periodic-op-mode: Haptic operation mode for FF_PERIODIC.
- Possible values:
- 1 - Register triggered waveform memory(RTWM) mode, the pattern
- 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.
-
-- dlg,nom-microvolt: Nominal actuator voltage rating.
- Valid values: 0 - 6000000.
-- dlg,abs-max-microvolt: Absolute actuator maximum voltage rating.
- Valid values: 0 - 6000000.
-- dlg,imax-microamp: Actuator max current rating.
- Valid values: 0 - 252000.
- Default: 130000.
-- dlg,impd-micro-ohms: the impedance of the actuator in micro ohms.
- Valid values: 0 - 1500000000.
-
-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.
- Valid range: 0 - 15.
-- 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.
- Valid range: 0 - 15.
-- dlg,gpiN-seq-id: the GPI(N)_SEQUENCE_ID, pattern to play
- when gpi0 is triggered, 'N' must be 0 - 2.
- Valid range: 0 - 15.
-- 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.
- the frequency range: 50 - 300.
- Default: 205.
-
-- 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: Customized waveform memory(patterns) data downloaded to
- the device during initialization. This is an array of 100 values(u8).
