Add the adis16486, adis16487 and adis16489 Six Degrees of Freedom Inertial Sensors to the list of compatible devices of the adis16480 iio subsystem driver. adis16486 is similar to adis16485, has the exact same channels but acceleration and delta velocity scales are different. adis16487 is fallback compatible with adis16485 and as a consequence, dt-bindings list was updated to use oneOf. adis16489 is similar to adis16488 but lacks the magnetometer and has a different accelerometer scale.

sync: In sync mode, the internal clock is disabled and the frequency

collection and processing. See Fig 14 and 15 in the datasheet.

The clock-frequency must be:

pps: In Pulse Per Second (PPS) Mode, the rate of data collection and

|
production is equal to the product of the external clock
|
|
frequency and the scale factor in the SYNC_SCALE register, see
|
|
Table 154 in the datasheet.
|
|
The clock-frequency must be:
|
|
* 1 to 128 Hz for adis1649x devices.
|
|
* This mode is not supported by adis1648x devices.

The DIOx line to be used as an external clock input.
|
|
Each DIOx pin supports only one function at a time (data ready line
|
|
selection or external clock input). When a single pin has two
|
|
two assignments, the enable bit for the lower priority function
|
|
automatically resets to zero (disabling the lower priority function).
|
|
Data ready has highest priority.
|
|
If not provided then DIO2 is assigned as default external clock
|
|
input pin.
