checkpatch.pl cleanups
Use scripts/checkpatch.pl to align code in staging/drivers/iio to Linux kernel coding style.

A directory (e.g. accel) is considered clean in the context of checkpatch.pl if running the following commands results in no warnings or errors:
scripts/checkpatch.pl -f drivers/staging/iio/accel/*.c
scripts/checkpatch.pl -f drivers/staging/iio/accel/*.h
scripts/checkpatch.pl -f drivers/staging/iio/accel/Kconfig
Please send us an email with the directory you want to work on. Don't forget to specify your full name and IRC handle.
Experimenting with IIO subsystem
For this we will use two kernel modules found in drivers/staging/iio:
iio_dummy_evgen.ko - generates fake events interrupts to be used by the iio_dummy example driver
implementation for this module is in iio_dummy_evgen.c
iio_dummy.ko - example IIO driver to demonstrate existing functionality
core implementation can be found in iio_simple_dummy.c
buffer functionality is implemented in iio_simple_dummy_buffer.c
events functionality is implemented in iio_simple_dummy_events.c
Dummy modules compilation
You need to select the following config options:
CONFIG_IIO_DUMMY_EVGEN} - for building iio_dummy_evgen kernel module
CONFIG_IIO_SIMPLE_DUMMY - for building iio_dummy kernel module
CONFIG_IIO_SIMPLE_DUMMY_EVENTS, CONFIG_IIO_SIMPLE_DUMMY_BUFFER should be selected for events and buffer functionality.
Use the following commands for modules compilation:
$ make drivers/staging/iio/iio_simple_dummy.ko
$ make drivers/staging/iio/iio_dummy.ko
IIO sysfs attributes
- TBA
IIO event monitor
IIO event monitor is an user space example application which reads events from IIO layer and pretty prints the results. Implementation can be found in iio_event_monitor.c under iio/drivers/staging/iio/Documentation. BR Task:
compile iio_event_monitor.c to obtain an executable called iio_event_monitor. Send an email with the command used for compilation to mentors listed at the top of the page.
