| 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). |

| 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. |

| 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. |
