^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 72) -----------
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 73)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 74) [From datasheet] The SMM665 is an Active DC Output power supply Controller
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 75) that monitors, margins and cascade sequences power. The part monitors six
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 76) power supply channels as well as VDD, 12V input, two general-purpose analog
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 77) inputs and an internal temperature sensor using a 10-bit ADC.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 78)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 79) Each monitored channel has its own high and low limits, plus a critical
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 80) limit.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 81)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 82) Support for SMM465, SMM764, and SMM766 has been implemented but is untested.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 88) This driver does not probe for devices, since there is no register which
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 89) can be safely used to identify the chip. You will have to instantiate
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 90) the devices explicitly. When instantiating the device, you have to specify
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 91) its configuration register address.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 92)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 93) Example: the following will load the driver for an SMM665 at address 0x57

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 103) This driver uses the values in the datasheet to convert ADC register values
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 104) into the values specified in the sysfs-interface document. All attributes are
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 105) read only.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 106)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 107) Min, max, lcrit, and crit values are used by the chip to trigger external signals
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 108) and/or other activity. Triggered signals can include HEALTHY, RST, Power Off,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 109) or Fault depending on the chip configuration. The driver reports values as lcrit
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 110) or crit if exceeding the limits triggers RST, Power Off, or Fault, and as min or
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 111) max otherwise. For details please see the SMM665 datasheet.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 112)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 113) For SMM465 and SMM764, values for Channel E and F are reported but undefined.
