^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 281) Description
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 282) -----------
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 283) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 284) The LM90 is a digital temperature sensor. It senses its own temperature as
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 285) well as the temperature of up to one external diode. It is compatible
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 286) with many other devices, many of which are supported by this driver.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 287) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 288) Note that there is no easy way to differentiate between the MAX6657,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 289) MAX6658 and MAX6659 variants. The extra features of the MAX6659 are only
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 290) supported by this driver if the chip is located at address 0x4d or 0x4e,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 291) or if the chip type is explicitly selected as max6659.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 292) The MAX6680 and MAX6681 only differ in their pinout, therefore they obviously
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 293) can't (and don't need to) be distinguished.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 294) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 295) The specificity of this family of chipsets over the ADM1021/LM84
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 296) family is that it features critical limits with hysteresis, and an
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 297) increased resolution of the remote temperature measurement.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 298) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 299) The different chipsets of the family are not strictly identical, although
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 300) very similar. For reference, here comes a non-exhaustive list of specific
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 301) features:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 302) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 303) LM90:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 304)   * Filter and alert configuration register at 0xBF.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 305)   * ALERT is triggered by temperatures over critical limits.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 306) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 307) LM86 and LM89:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 308)   * Same as LM90
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 309)   * Better external channel accuracy
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 310)

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 366) All temperature values are given in degrees Celsius. Resolution
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 367) is 1.0 degree for the local temperature, 0.125 degree for the remote
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 368) temperature, except for the MAX6654, MAX6657, MAX6658 and MAX6659 which have
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 369) a resolution of 0.125 degree for both temperatures.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 371) Each sensor has its own high and low limits, plus a critical limit.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 372) Additionally, there is a relative hysteresis value common to both critical
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 373) values. To make life easier to user-space applications, two absolute values
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 374) are exported, one for each channel, but these values are of course linked.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 375) Only the local hysteresis can be set from user-space, and the same delta
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 376) applies to the remote hysteresis.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 377) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 378) The lm90 driver will not update its values more frequently than configured with
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 379) the update_interval attribute; reading them more often will do no harm, but will
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 380) return 'old' values.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 382) SMBus Alert Support
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 383) -------------------
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 384) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 385) This driver has basic support for SMBus alert. When an alert is received,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 386) the status register is read and the faulty temperature channel is logged.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 387) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 388) The Analog Devices chips (ADM1032, ADT7461 and ADT7461A) and ON
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 389) Semiconductor chips (NCT1008) do not implement the SMBus alert protocol
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 390) properly so additional care is needed: the ALERT output is disabled when
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 391) an alert is received, and is re-enabled only when the alarm is gone.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 392) Otherwise the chip would block alerts from other chips in the bus as long
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 393) as the alarm is active.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 394) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 395) PEC Support
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 396) -----------
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 397) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 398) The ADM1032 is the only chip of the family which supports PEC. It does
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 399) not support PEC on all transactions though, so some care must be taken.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 400) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 401) When reading a register value, the PEC byte is computed and sent by the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 402) ADM1032 chip. However, in the case of a combined transaction (SMBus Read
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 403) Byte), the ADM1032 computes the CRC value over only the second half of
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 404) the message rather than its entirety, because it thinks the first half
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 405) of the message belongs to a different transaction. As a result, the CRC
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 406) value differs from what the SMBus master expects, and all reads fail.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 407) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 408) For this reason, the lm90 driver will enable PEC for the ADM1032 only if
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 409) the bus supports the SMBus Send Byte and Receive Byte transaction types.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 410) These transactions will be used to read register values, instead of
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 411) SMBus Read Byte, and PEC will work properly.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 412) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 413) Additionally, the ADM1032 doesn't support SMBus Send Byte with PEC.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 414) Instead, it will try to write the PEC value to the register (because the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 415) SMBus Send Byte transaction with PEC is similar to a Write Byte transaction
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 416) without PEC), which is not what we want. Thus, PEC is explicitly disabled
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 417) on SMBus Send Byte transactions in the lm90 driver.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 418) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 419) PEC on byte data transactions represents a significant increase in bandwidth
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 420) usage (+33% for writes, +25% for reads) in normal conditions. With the need
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 421) to use two SMBus transaction for reads, this overhead jumps to +50%. Worse,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 422) two transactions will typically mean twice as much delay waiting for
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 423) transaction completion, effectively doubling the register cache refresh time.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 424) I guess reliability comes at a price, but it's quite expensive this time.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 425) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 426) So, as not everyone might enjoy the slowdown, PEC can be disabled through
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 427) sysfs. Just write 0 to the "pec" file and PEC will be disabled. Write 1
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 428) to that file to enable PEC again.
