Description
|
||||
-----------
|
||||
|
||||
This driver supports hardware monitoring for Texas Instruments TPS23861 PoE PSE.
|
||||
|
||||
TPS23861 is a quad port IEEE802.3at PSE controller with optional I2C control
|
||||
and monitoring capabilities.
|
||||
|
||||
TPS23861 offers three modes of operation: Auto, Semi-Auto and Manual.
|
||||
|
||||
This driver only supports the Auto mode of operation providing monitoring
|
||||
as well as enabling/disabling the four ports.
