ltc2990: Linear Technology LTC2990 power monitor
|
|
|
|
Required properties:
|
|
- compatible: Must be "lltc,ltc2990"
|
|
- reg: I2C slave address
|
|
- lltc,meas-mode:
|
|
An array of two integers for configuring the chip measurement mode.
|
|
|
|
The first integer defines the bits 2..0 in the control register. In all
|
|
cases the internal temperature and supply voltage are measured. In
|
|
addition the following input measurements are enabled per mode:
|
|
|
|
0: V1, V2, TR2
|
|
1: V1-V2, TR2
|
|
2: V1-V2, V3, V4
|
|
3: TR1, V3, V4
|
|
4: TR1, V3-V4
|
|
5: TR1, TR2
|
|
6: V1-V2, V3-V4
|
|
7: V1, V2, V3, V4
|
|
|
|
The second integer defines the bits 4..3 in the control register. This
|
|
allows a subset of the measurements to be enabled:
|
|
|
|
0: Internal temperature and supply voltage only
|
|
1: TR1, V1 or V1-V2 only per mode
|
|
2: TR2, V3 or V3-V4 only per mode
|
|
3: All measurements per mode
|
|
|
|
Example:
|
|
|
|
ltc2990@4c {
|
|
compatible = "lltc,ltc2990";
|
|
reg = <0x4c>;
|
|
lltc,meas-mode = <7 3>; /* V1, V2, V3, V4 */
|
|
};
