		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>;
		};

		Description
		-----------

		This driver implements support for several MAX6697 compatible temperature sensor
		chips. The chips support one local temperature sensor plus four, six, or seven
		remote temperature sensors. Remote temperature sensors are diode-connected
		thermal transitors, except for MAX6698 which supports three diode-connected
		thermal transistors plus three thermistors in addition to the local temperature
		sensor.

		The driver provides the following sysfs attributes. temp1 is the local (chip)
		temperature, temp[2..n] are remote temperatures. The actually supported
		per-channel attributes are chip type and channel dependent.

		tempX_input RO temperature
		tempX_max RW temperature maximum threshold
		tempX_max_alarm RO temperature maximum threshold alarm
		tempX_crit RW temperature critical threshold
		tempX_crit_alarm RO temperature critical threshold alarm
		tempX_fault RO temperature diode fault (remote sensors only)
