This series revives some older patches from a few months back which somehow fell off the table. It introduces two helper functions for managing triggered buffers, since almost all drivers which use triggered buffers have the same code for setting up and registering the pollfunc and trigger. New in this series is that the helper functions now only support kfifo buffers. So only these drivers which do use a kfifo buffer have been converted. There are a few more drivers which could make use of these helper functions if we switch them from the swring buffer to the kfifo buffer. Also new in this series is that the helper functions are now in their own module, since it has dependencies on IIO_BUFFER, IIO_KFIFO_BUF and IIO_TRIGGER_BUF but neither of these have on each other. So putting the helper functions in one of these modules would add a dependency of the other modules to that module. - Lars Lars-Peter Clausen (9): iio: Add helper function for initializing triggered buffers iio:adc:at91: Use new triggered buffer setup helper staging:iio:adc:ad7192: Use new triggered buffer setup helper function staging:iio:adc:ad7298: Use new triggered buffer setup helper function staging:iio:adc:ad7476: Use new triggered buffer setup helper function staging:iio:adc:ad7606: Use new triggered buffer setup helper function staging:iio:adc:ad7793: Use new triggered buffer setup helper function staging:iio:adc:ad7887: Use new triggered buffer setup helper function staging:iio:adc:ad799x: Use new triggered buffer setup helper function drivers/iio/Kconfig | 7 ++ drivers/iio/Makefile | 1 + drivers/iio/adc/Kconfig | 2 +- drivers/iio/adc/at91_adc.c | 49 +----------- drivers/iio/industrialio-triggered-buffer.c | 109 +++++++++++++++++++++++++++ drivers/staging/iio/adc/Kconfig | 7 ++ drivers/staging/iio/adc/ad7192.c | 47 ++---------- drivers/staging/iio/adc/ad7298.h | 5 ++ drivers/staging/iio/adc/ad7298_core.c | 11 +-- drivers/staging/iio/adc/ad7298_ring.c | 62 +++------------ drivers/staging/iio/adc/ad7476_core.c | 9 --- drivers/staging/iio/adc/ad7476_ring.c | 44 +---------- drivers/staging/iio/adc/ad7606_core.c | 9 --- drivers/staging/iio/adc/ad7606_ring.c | 44 +---------- drivers/staging/iio/adc/ad7793.c | 47 ++---------- drivers/staging/iio/adc/ad7887_core.c | 9 --- drivers/staging/iio/adc/ad7887_ring.c | 33 +------- drivers/staging/iio/adc/ad799x.h | 2 - drivers/staging/iio/adc/ad799x_core.c | 25 +++--- drivers/staging/iio/adc/ad799x_ring.c | 63 +--------------- include/linux/iio/buffer.h | 7 ++ 21 files changed, 189 insertions(+), 403 deletions(-) create mode 100644 drivers/iio/industrialio-triggered-buffer.c -- 1.7.10 -- To unsubscribe from this list: send the line "unsubscribe linux-iio" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
