^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 88) Description
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 89) -----------
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 90)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 91) This driver supports hardware monitoring for various PMBus compliant devices.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 92) It supports voltage, current, power, and temperature sensors as supported
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 93) by the device.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 94)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 95) Each monitored channel has its own high and low limits, plus a critical
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 96) limit.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 97)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 98) Fan support will be added in a later version of this driver.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 100)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 101) Usage Notes
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 102) -----------
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 103)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 104) This driver does not probe for PMBus devices, since there is no register
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 105) which can be safely used to identify the chip (The MFG_ID register is not
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 106) supported by all chips), and since there is no well defined address range for
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 107) PMBus devices. You will have to instantiate the devices explicitly.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 108)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 109) Example: the following will load the driver for an LTC2978 at address 0x60
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 110) on I2C bus #1::
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 111)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 112) $ modprobe pmbus
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 113) $ echo ltc2978 0x60 > /sys/bus/i2c/devices/i2c-1/new_device

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 118)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 119) Support for additional PMBus chips can be added by defining chip parameters in
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 120) a new chip specific driver file. For example, (untested) code to add support for
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 121) Emerson DS1200 power modules might look as follows::

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 187) When probing the chip, the driver identifies which PMBus registers are
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 188) supported, and determines available sensors from this information.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 189) Attribute files only exist if respective sensors are supported by the chip.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 190) Labels are provided to inform the user about the sensor associated with
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 191) a given sysfs entry.
