2013-10-12iio: Factor IIO value formating into its own functionLars-Peter Clausen1-0/+2

2013-10-12iio: Add a helper to free a list of IIO device attributesLars-Peter Clausen1-0/+1
We have the same code to free a IIO device attribute list in multiple place. This patch adds a new helper function to take care of this and replaces the custom instances with a call to the helper function. Note that we do not need to call list_del() for each of the list items since we will never look at any of the list items nor the list itself again.

2013-10-12iio: Wakeup poll and blocking reads when the device is unregisteredLars-Peter Clausen1-0/+3
Once the device has been unregistered there won't be any new data no matter how long a userspace application waits, so we might as well wake them up and let them know. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2013-09-25Merge 3.12-rc2 into staging-next.Greg Kroah-Hartman1-0/+4
This resolves the merge problem with two iio drivers that Stephen Rothwell pointed out. Reported-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2013-09-21iio: Stop sampling when the device is removedLars-Peter Clausen1-0/+4
Make sure to stop sampling when the device is removed, otherwise it will continue to sample forever. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2013-09-15iio: refactor info mask and ext_info attribute creation.Jonathan Cameron1-1/+1
Introduce an enum to specify whether the attribute is separate or shared. Factor out the bitmap handling for loop into a separate function. Tidy up error handling and add a NULL assignment to squish a false positive warning from GCC. Change ext_info shared type from boolean to enum and update in all drivers.

2013-03-16iio: Add OF supportGuenter Roeck1-0/+1
Provide bindings and parse OF data during initialization. Signed-off-by: Guenter Roeck <linux@roeck-us.net> Reviewed-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2012-04-25IIO: Move the core files to drivers/iioJonathan Cameron1-0/+62
Take the core support + the kfifo buffer implentation out of staging. Whilst we are far from done in improving this subsystem it is now at a stage where the userspae interfaces (provided by the core) can be considered stable. Drivers will follow over a longer time scale. Signed-off-by: Jonathan Cameron <jic23@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
