max6697 properties
Required properties:
- compatible:
Should be one of
maxim,max6581
maxim,max6602
maxim,max6622
maxim,max6636
maxim,max6689
maxim,max6693
maxim,max6694
maxim,max6697
maxim,max6698
maxim,max6699
- reg: I2C address
Optional properties:
- smbus-timeout-disable
Set to disable SMBus timeout. If not specified, SMBus timeout will be
enabled.
- extended-range-enable
Only valid for MAX6581. Set to enable extended temperature range.
Extended temperature will be disabled if not specified.
- beta-compensation-enable
Only valid for MAX6693 and MX6694. Set to enable beta compensation on
remote temperature channel 1.
Beta compensation will be disabled if not specified.
- alert-mask
Alert bit mask. Alert disabled for bits set.
Select bit 0 for local temperature, bit 1..7 for remote temperatures.
If not specified, alert will be enabled for all channels.
- over-temperature-mask
Over-temperature bit mask. Over-temperature reporting disabled for
bits set.
Select bit 0 for local temperature, bit 1..7 for remote temperatures.
If not specified, over-temperature reporting will be enabled for all
channels.
- resistance-cancellation
Boolean for all chips other than MAX6581. Set to enable resistance
cancellation on remote temperature channel 1.
For MAX6581, resistance cancellation enabled for all channels if
specified as boolean, otherwise as per bit mask specified.
Only supported for remote temperatures (bit 1..7).
If not specified, resistance cancellation will be disabled for all
channels.
- transistor-ideality
For MAX6581 only. Two values; first is bit mask, second is ideality
select value as per MAX6581 data sheet. Select bit 1..7 for remote
channels.
Transistor ideality will be initialized to default (1.008) if not
specified.
Example:
temp-sensor@1a {
compatible = "maxim,max6697";
reg = <0x1a>;
smbus-timeout-disable;
resistance-cancellation;
alert-mask = <0x72>;
over-temperature-mask = <0x7f>;
};
