This patchset is based on the new multibuffer set. It doesn't require the high-speed/mmap interface. That will come later on a v2. Changelog v1 -> v2: * https://lore.kernel.org/linux-iio/20210212102021.47276-4-alexandru.ardelean@xxxxxxxxxx/T/#u * removed DMA patches for now * in patch 'iio: Add output buffer support' - added /sys/bus/iio/devices/iio:deviceX/bufferY/direction attribute - thinking about this, an update to the new buffer infrastructure is required when adding ADDAC/MxFE/transceivers; right now there is no problem, because we have only ADCs and DACs; but when we get transceivers, a bufferY/ directory needs to filter in/out scan_elements/ ; this only occured to me recently (it's one of those things that pops up later in mind) * added 'iio: Documentation: update definitions for bufferY and scan_elements' - seems I forgot this on the original multibuffer patchset * added 'iio: triggered-buffer: extend support to configure output buffers' - basically output triggered buffer support * added 'iio: dac: ad5686: Add PWM as a trigger source' - this is a first user of this infrastructure Alexandru Ardelean (2): iio: Documentation: update definitions for bufferY and scan_elements iio: triggered-buffer: extend support to configure output buffers Lars-Peter Clausen (2): iio: Add output buffer support iio: kfifo-buffer: Add output buffer support Mircea Caprioru (1): iio: dac: ad5686: Add PWM as a trigger source Documentation/ABI/testing/sysfs-bus-iio | 92 +++++++++++ drivers/iio/accel/adxl372.c | 1 + drivers/iio/accel/bmc150-accel-core.c | 1 + drivers/iio/adc/at91-sama5d2_adc.c | 4 +- .../buffer/industrialio-triggered-buffer.c | 8 +- drivers/iio/buffer/kfifo_buf.c | 50 ++++++ .../cros_ec_sensors/cros_ec_sensors_core.c | 1 + .../common/hid-sensors/hid-sensor-trigger.c | 5 +- drivers/iio/dac/ad5686-spi.c | 2 +- drivers/iio/dac/ad5686.c | 146 +++++++++++++++++- drivers/iio/dac/ad5686.h | 7 +- drivers/iio/dac/ad5696-i2c.c | 2 +- drivers/iio/industrialio-buffer.c | 128 ++++++++++++++- include/linux/iio/buffer.h | 7 + include/linux/iio/buffer_impl.h | 11 ++ include/linux/iio/triggered_buffer.h | 11 +- 16 files changed, 459 insertions(+), 17 deletions(-) -- 2.17.1
