menuconfig PSE_CONTROLLER
bool "Ethernet Power Sourcing Equipment Support"
depends on REGULATOR
help
Generic Power Sourcing Equipment Controller support.
If unsure, say no.
if PSE_CONTROLLER
config PSE_REALTEK_MCU
tristate
help
Shared core for the Realtek PSE MCU driver. This is selected
automatically by the transport options below.
config PSE_REALTEK_MCU_I2C
tristate "Realtek PSE MCU driver (I2C transport)"
depends on I2C
select PSE_REALTEK_MCU
help
Driver for the microcontroller (MCU) that fronts the PSE
hardware on various Realtek-based managed switches, attached
via I2C/SMBus. The MCU exposes a message-based protocol; the actual
PSE silicon is not accessed directly. To compile this driver as a
module, choose M here: the module will be called realtek-pse-mcu-i2c.
config PSE_REALTEK_MCU_UART
tristate "Realtek PSE MCU driver (UART transport)"
depends on SERIAL_DEV_BUS
select PSE_REALTEK_MCU
help
Driver for the microcontroller (MCU) that fronts the PSE
hardware on various Realtek-based managed switches, attached
via UART. The MCU exposes a message-based protocol; the actual PSE
silicon is not accessed directly. To compile this driver as a
module, choose M here: the module will be called realtek-pse-mcu-uart.
config PSE_REGULATOR
tristate "Regulator based PSE controller"
help
This module provides support for simple regulator based Ethernet Power
Sourcing Equipment without automatic classification support. For
example for basic implementation of PoDL (802.3bu) specification.
config PSE_PD692X0
tristate "PD692X0 PSE controller"
depends on I2C
select FW_LOADER
select FW_UPLOAD
help
This module provides support for PD692x0 regulator based Ethernet
Power Sourcing Equipment.
To compile this driver as a module, choose M here: the
module will be called pd692x0.
config PSE_SI3474
tristate "Si3474 PSE controller"
depends on I2C
help
This module provides support for Si3474 regulator based Ethernet
Power Sourcing Equipment.
Only 4-pair PSE configurations are supported.
To compile this driver as a module, choose M here: the
module will be called si3474.
config PSE_TPS23881
tristate "TPS23881 PSE controller"
depends on I2C
help
This module provides support for TPS23881 regulator based Ethernet
Power Sourcing Equipment.
To compile this driver as a module, choose M here: the
module will be called tps23881.
