config W1_SLAVE_THERM
tristate "Thermal family implementation"
help
Say Y here if you want to connect 1-wire thermal sensors to your
wire.
config W1_SLAVE_SMEM
tristate "Simple 64bit memory family implementation"
help
Say Y here if you want to connect 1-wire
simple 64bit memory rom(ds2401/ds2411/ds1990*) to your wire.
config W1_SLAVE_DS2405
tristate "DS2405 Addressable Switch"
help
Say Y or M here if you want to use a DS2405 1-wire
single-channel addressable switch.
This device can also work as a single-channel
binary remote sensor.
config W1_SLAVE_DS2408
tristate "8-Channel Addressable Switch (IO Expander) 0x29 family support (DS2408)"
help
Say Y here if you want to use a 1-wire
DS2408 8-Channel Addressable Switch device support
config W1_SLAVE_DS2408_READBACK
bool "Read-back values written to DS2408's output register"
depends on W1_SLAVE_DS2408
default y
help
Enabling this will cause the driver to read back the values written
to the chip's output register in order to detect errors.
This is slower but useful when debugging chips and/or busses.
config W1_SLAVE_DS2413
tristate "Dual Channel Addressable Switch 0x3a family support (DS2413)"
help
Say Y here if you want to use a 1-wire
DS2413 Dual Channel Addressable Switch device support
config W1_SLAVE_DS2406
tristate "Dual Channel Addressable Switch 0x12 family support (DS2406)"
select CRC16
help
Say Y or M here if you want to use a 1-wire
DS2406 Dual Channel Addressable Switch. EPROM read/write
support for these devices is not implemented.
config W1_SLAVE_DS2423
tristate "Counter 1-wire device (DS2423)"
select CRC16
help
If you enable this you can read the counter values available
in the DS2423 chipset from the w1_slave file under the
sys file system.
Say Y here if you want to use a 1-wire
counter family device (DS2423).
config W1_SLAVE_DS2805
tristate "112-byte EEPROM support (DS28E05)"
help
Say Y here if you want to use a 1-wire
is a 112-byte user-programmable EEPROM is
organized as 7 pages of 16 bytes each with 64bit
unique number. Requires OverDrive Speed to talk to.
config W1_SLAVE_DS2430
tristate "256b EEPROM family support (DS2430)"
help
Say Y here if you want to use a 1-wire 256bit EEPROM
family device (DS2430).
This EEPROM is organized as one page of 32 bytes for random
access.
config W1_SLAVE_DS2431
tristate "1kb EEPROM family support (DS2431)"
help
Say Y here if you want to use a 1-wire
1kb EEPROM family device (DS2431)

Say Y here if you want to use a 1-wire
4kb EEPROM family device (DS2433).
config W1_SLAVE_DS2433_CRC
bool "Protect DS2433 data with a CRC16"
depends on W1_SLAVE_DS2433
select CRC16
help
Say Y here to protect DS2433 data with a CRC16.
Each block has 30 bytes of data and a two byte CRC16.
Full block writes are only allowed if the CRC is valid.

512b/1kb/16kb EPROM family device (DS250x).
config W1_SLAVE_DS2780
tristate "Dallas 2780 battery monitor chip"
help
If you enable this you will have the DS2780 battery monitor
chip support.
The battery monitor chip is used in many batteries/devices
as the one who is responsible for charging/discharging/monitoring
Li+ batteries.
If you are unsure, say N.
config W1_SLAVE_DS2781
tristate "Dallas 2781 battery monitor chip"
help
If you enable this you will have the DS2781 battery monitor
chip support.

config W1_SLAVE_DS28E04
tristate "4096-Bit Addressable 1-Wire EEPROM with PIO (DS28E04-100)"
select CRC16
help
If you enable this you will have the DS28E04-100
chip support.
Say Y here if you want to use a 1-wire
4kb EEPROM with PIO family device (DS28E04).
If you are unsure, say N.
config W1_SLAVE_DS28E17
tristate "1-wire-to-I2C master bridge (DS28E17)"
select CRC16
depends on I2C
help
Say Y here if you want to use the DS28E17 1-wire-to-I2C master bridge.
For each DS28E17 detected, a new I2C adapter is created within the
kernel. I2C devices on that bus can be configured to be used by the
kernel and userspace tools as on any other "native" I2C bus.
This driver is also available as a module. If so, the module
will be called w1_ds28e17.
If you are unsure, say N.
