#
config ADC
bool "Analog-to-Digital Conversion"
default n
---help---
Select to enable support for analog input device support. This includes
not only Analog-to-Digital Converters (ADC) but also amplifiers and
analog multiplexers.
config ADC_ADS125X
bool "TI ADS1255/ADS1256 support"
default n
depends on ADC
select SPI
config ADS1255_FREQUENCY
int "ADS1255/ADS1256 SPI frequency"
default 1000000
depends on ADC_ADS125X
config ADC_PGA11X
bool "TI PGA112/3/6/7 support"
default n
depends on ADC
select SPI
---help---
Enables support for the PGA112, PGA113, PGA116, PGA117 Zer�-Drift
PROGRAMMABLE GAIN AMPLIFIER with MUX
config PGA11X_SPIFREQUENCY
int "TI PGA112/3/6/7 SPI frequency"
default 1000000
depends on ADC_PGA11X
---help---
PGA11x SPI frequency.
config PGA11X_SPIMODE
int "TI PGA112/3/6/7 SPI mode"
default 0
depends on ADC_PGA11X
---help---
PGA11x SPI mode. The specification says that the device operates in Mode 0 or
Mode 3. But sometimes you need to tinker with this to get things to work
correctly. Default: Mode 0
config PGA11X_DAISYCHAIN
bool "TI PGA112/3/6/7 daisy chain mode"
default n
depends on ADC_PGA11X
---help---
Enable support to use two PGA116/7's in Daisy Chain configuration.
config PGA11X_MULTIPLE
bool "Multiple TI PGA112/3/6/7 support"
default n
depends on ADC_PGA11X && !PGA11X_DAISYCHAIN
---help---
Can be defined to support multiple PGA11X devices on board with separate
chip selects (not daisy chained). Each device will require a customized
SPI interface to distinguish them when SPI_SELECT is called with
devid=SPIDEV_MUX.
config DAC
bool "Digital-to-Analog Conversion"
default n
---help---
Select to enable support for Digital-to-Analog Converters (DACs).
config DAC_AD5410
bool "AD5410 support"
default n
depends on DAC
select SPI
