18 Description
19 -----------
20
21 This driver implements support for the MCP998X family containing: MCP9982,
22 MCP9982D, MCP9983, MCP9983D, MCP9984, MCP9984D, MCP9985, MCP9985D,
23 MCP9933 and MCP9933D.
24
25 The MCP998X Family is a high accuracy 2-wire multichannel automotive
26 temperature monitor.
27
28 The chips in the family have different numbers of external channels,
29 ranging from 1 (MCP9982) to 4 channels (MCP9985). Reading diodes in
30 anti-parallel connection is supported by MCP9984/85/33 and
31 MCP9984D/85D/33D. Dedicated hardware shutdown circuitry is present
32 only in MCP998XD and MCP9933D.
33
34 Temperatures are read in millidegrees Celsius, ranging from -64 to
35 191.875 with 0.125 precision.
36
37 Each channel has a minimum, maximum, and critical limit alongside associated alarms.
38 The chips also implement a hysteresis mechanism which applies only to the maximum
39 and critical limits. The relative difference between a limit and its hysteresis
40 is the same for both and the value is kept in a single register.
41
42 The chips measure temperatures with a variable conversion rate.
43 Update_interval = Conversion/Second, so the available options are:
44 - 16000 (ms) = 1 conv/16 sec
45 - 8000 (ms) = 1 conv/8 sec
46 - 4000 (ms) = 1 conv/4 sec
47 - 2000 (ms) = 1 conv/2 sec
48 - 1000 (ms) = 1 conv/sec
49 - 500 (ms) = 2 conv/sec
50 - 250 (ms) = 4 conv/sec
51 - 125 (ms) = 8 conv/sec
52 - 64 (ms) = 16 conv/sec
53 - 32 (ms) = 32 conv/sec
54 - 16 (ms) = 64 conv/sec
55
56 Usage Notes
57 -----------
58
59 Parameters that can be configured in devicetree:
60 - anti-parallel diode mode operation
61 - resistance error correction on channels 1 and 2
62 - resistance error correction on channels 3 and 4
63 Chips 82/83 and 82D/83D do not support anti-parallel diode mode.
64 For chips with "D" in the name resistance error correction must be on.
65 Please see Documentation/devicetree/bindings/hwmon/microchip,mcp9982.yaml
66 for details.
67
68 There are two power states:
69 - Active state: in which the chip is converting on all channels at the
70 programmed rate.
> 71 - Standby state: in which the host must initiate a conversion cycle.
> 72 Chips with "D" in the name work in Active state only and those without
73 can work in either state.
