34 Accepted interrupt types are:
35 * IRQ_TYPE_EDGE_RISING
36 * IRQ_TYPE_EDGE_FALLING
42 Default if not supplied is DIO1.
55 description: Connected to RESET pin which is active low.
59 description: If not provided, then the internal clock is used.
63 sync: In sync mode, the internal clock is disabled and the frequency
64 of the external clock signal establishes therate of data
65 collection and processing. See Fig 14 and 15 in the datasheet.
66 The clock-frequency must be:
67 * 3000 to 4500 Hz for adis1649x devices.
68 * 700 to 2400 Hz for adis1648x devices.
69 pps: In Pulse Per Second (PPS) Mode, the rate of data collection and
70 production is equal to the product of the external clock
71 frequency and the scale factor in the SYNC_SCALE register, see
72 Table 154 in the datasheet.
73 The clock-frequency must be:
74 * 1 to 128 Hz for adis1649x devices.
75 * This mode is not supported by adis1648x devices.

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