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>;
};
