18Optional properties:
19
20- smbus-timeout-disable
21	Set to disable SMBus timeout. If not specified, SMBus timeout will be
22	enabled.
23- extended-range-enable
24	Only valid for MAX6581. Set to enable extended temperature range.
25	Extended temperature will be disabled if not specified.
26- beta-compensation-enable
27	Only valid for MAX6693 and MX6694. Set to enable beta compensation on
28	remote temperature channel 1.
29	Beta compensation will be disabled if not specified.
30- alert-mask
31	Alert bit mask. Alert disabled for bits set.
32	Select bit 0 for local temperature, bit 1..7 for remote temperatures.
33	If not specified, alert will be enabled for all channels.
34- over-temperature-mask
35	Over-temperature bit mask. Over-temperature reporting disabled for
36	bits set.
37	Select bit 0 for local temperature, bit 1..7 for remote temperatures.
38	If not specified, over-temperature reporting will be enabled for all
39	channels.
40- resistance-cancellation
41	Boolean for all chips other than MAX6581. Set to enable resistance
42	cancellation on remote temperature channel 1.
43	For MAX6581, resistance cancellation enabled for all channels if
44	specified as boolean, otherwise as per bit mask specified.
45	Only supported for remote temperatures (bit 1..7).
46	If not specified, resistance cancellation will be disabled for all
47	channels.
48- transistor-ideality
49	For MAX6581 only. Two values; first is bit mask, second is ideality
50	select value as per MAX6581 data sheet. Select bit 1..7 for remote
51	channels.
52	Transistor ideality will be initialized to default (1.008) if not
53	specified.

61	resistance-cancellation;
62	alert-mask = <0x72>;
63	over-temperature-mask = <0x7f>;
