# Industrial I/O subsytem configuration
#
menuconfig IIO
tristate "Industrial I/O support"
depends on GENERIC_HARDIRQS
help
The industrial I/O subsystem provides a unified framework for
drivers for many different types of embedded sensors using a
number of different physical interfaces (i2c, spi, etc). See
drivers/staging/iio/Documentation for more information.
if IIO
config IIO_BUFFER
bool "Enable buffer support within IIO"
help
Provide core support for various buffer based data
acquisition methods.
if IIO_BUFFER
config IIO_SW_RING
select IIO_TRIGGER
tristate "Industrial I/O lock free software ring"
help
Example software ring buffer implementation. The design aim
of this particular realization was to minimize write locking
with the intention that some devices would be able to write
in interrupt context.
config IIO_KFIFO_BUF
select IIO_TRIGGER
tristate "Industrial I/O buffering based on kfifo"
help
A simple fifo based on kfifo. Use this if you want a fifo
rather than a ring buffer. Note that this currently provides
no buffer events so it is up to userspace to work out how
often to read from the buffer.
endif # IIO_BUFFER
config IIO_TRIGGER
boolean "Enable triggered sampling support"
help
Provides IIO core support for triggers. Currently these
are used to initialize capture of samples to push into
ring buffers. The triggers are effectively a 'capture
data now' interrupt.
config IIO_CONSUMERS_PER_TRIGGER
int "Maximum number of consumers per trigger"
depends on IIO_TRIGGER
default "2"
help
This value controls the maximum number of consumers that a
given trigger may handle. Default is 2.

config IIO_SIMPLE_DUMMY
tristate "An example driver with no hardware requirements"
help
Driver intended mainly as documentation for how to write
a driver. May also be useful for testing userspace code
without hardward.
if IIO_SIMPLE_DUMMY
config IIO_SIMPLE_DUMMY_EVENTS
boolean "Event generation support"
select IIO_DUMMY_EVGEN
help
Add some dummy events to the simple dummy driver.
config IIO_SIMPLE_DUMMY_BUFFER
boolean "Buffered capture support"
depends on IIO_KFIFO_BUF
help
Add buffered data capture to the simple dummy driver.
