Description
-----------
[From datasheets] The MAX16065/MAX16066 flash-configurable system managers
monitor and sequence multiple system voltages. The MAX16065/MAX16066 can also
accurately monitor (+/-2.5%) one current channel using a dedicated high-side
current-sense amplifier. The MAX16065 manages up to twelve system voltages
simultaneously, and the MAX16066 manages up to eight supply voltages.
The MAX16067 flash-configurable system manager monitors and sequences multiple
system voltages. The MAX16067 manages up to six system voltages simultaneously.
The MAX16068 flash-configurable system manager monitors and manages up to six
system voltages simultaneously.
The MAX16070/MAX16071 flash-configurable system monitors supervise multiple
system voltages. The MAX16070/MAX16071 can also accurately monitor (+/-2.5%)
one current channel using a dedicated high-side current-sense amplifier. The
MAX16070 monitors up to twelve system voltages simultaneously, and the MAX16071
monitors up to eight supply voltages.
Each monitored channel has its own low and high critical limits. MAX16065,
MAX16066, MAX16070, and MAX16071 support an additional limit which is
configurable as either low or high secondary limit. MAX16065, MAX16066,
MAX16070, and MAX16071 also support supply current monitoring.
Usage Notes
-----------
This driver does not probe for devices, since there is no register which
can be safely used to identify the chip. You will have to instantiate
the devices explicitly. Please see Documentation/i2c/instantiating-devices.rst for
details.
WARNING: Do not access chip registers using the i2cdump command, and do not use
any of the i2ctools commands on a command register (0xa5 to 0xac). The chips
supported by this driver interpret any access to a command register (including
read commands) as request to execute the command in question. This may result in
power loss, board resets, and/or Flash corruption. Worst case, your board may
turn into a brick.

MAX16065-16071 채널 구성과 명령 레지스터 경고
1-84드라이버는 `max16065`, `max16066`, `max16067`, `max16068`, `max16070`, `max16071` 접두사의 플래시 구성 가능 시스템 관리자·모니터를 지원하며 저자는 Guenter Roeck입니다. 주소 자동 탐색은 없습니다.
MAX16065는 최대 12개, MAX16066은 최대 8개 공급 전압을 동시에 관리하며 전용 하이사이드 전류 감지 증폭기로 전류 채널 하나를 ±2.5% 정확도로 감시합니다. MAX16067과 MAX16068은 최대 6개 전압을 관리합니다. MAX16070은 최대 12개, MAX16071은 최대 8개 전압과 전류 채널 하나를 감시합니다.
모든 채널에는 저·고 임계 한계가 있습니다. MAX16065/16066/16070/16071은 저 또는 고 보조 한계 중 하나와 공급 전류 감시를 추가로 지원합니다.
안전한 식별 레지스터가 없어 장치를 명시적으로 생성해야 합니다. `i2cdump`를 사용하거나 명령 레지스터 `0xa5-0xac`에 어떤 i2ctools 명령도 실행하면 안 됩니다. 이 칩은 읽기를 포함한 모든 접근을 해당 명령 실행 요청으로 해석하여 전원 손실, 보드 리셋, Flash 손상이나 최악의 경우 복구 불능 보드를 만들 수 있습니다.
장치별 전압 수와 전류 감시 지원입니다.
위험한 명령 레지스터를 피하고 드라이버 인터페이스만 사용합니다.

전압 채널·보조 한계와 선택적 전류 감시
85-127`in[0-11]_input`은 입력 전압 측정값입니다. `in12_input`은 전류 감지를 지원하고 활성화한 칩에서만 CSP(Current Sense Positive) 핀 전압을 제공합니다.
`in[0-11]_min`과 `max`는 MAX16065/16066/16070/16071에서만 제공되는 저·고 경고 한계입니다. 칩 설정에 따라 저 또는 고 경고 한계 중 하나만 지원하며 둘을 동시에 제공하지 않습니다. `lcrit`과 `crit`은 모든 해당 채널의 저·고 임계 한계이고 `alarm`은 입력 전압 알람입니다.
`curr1_input`과 `curr1_alarm`은 전류 감지 기능을 지원하고 활성화한 경우에만 나타납니다. 표시 전류는 0.001 Ohm, 즉 1 mOhm 전류 감지 저항을 가정합니다.
