Changes since V1: Apply Jonathan's review feedback: Revise device status attribute names, and split documentation into two sections. Add additional comments, and fix indention issues. Remove pointless zero initializations. Revise return value handling. Simplify some code sections. Split store_eeprom and sync handling into separate functions. Use strtobool where applicable. Document platform data structures using kernel-doc style. Use dev_to_iio_dev write_raw IIO_CHAN_INFO_FREQUENCY: Reject values <= 0 Make patch target drivers/iio Changes since V2: Use for_each_clear_bit() and __set_bit() where applicable. Add descriptive comment. Avoid temporary for struct regulator. spi_device_id name use ad9523-1, ad9523 will be added later.

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
|
|
Documentation/iio for more information.

|

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.

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.

This value controls the maximum number of consumers that a
