This patch implements the hardware triggers support and buffer management for sama5d2. The DT modifications ( [PATCH 1/3] ARM: dts: at91: sama5d2_xplained: enable ADTRG pin) are for demonstration purposes of the feature, setting the pinctrl for the ADC hw trigger pin,should go through at91 maintainers. I also increased the buffer size for the trigger name in the generic_buffer application to cope with longer names and avoid stack smashing problem. This is in patch [PATCH 3/3] iio: tools: generic_buffer: increase trigger length Changes in v2: - Moved buffer allocation and freeing into the preenable and postdisable callbacks. We have a total of scan bytes that can vary a lot depending on each channel enabled at a certain point. - made the at91 trigger list part of state structure - made the iio trigger list preallocated in state structure - moved irq enabling/disabling into the try_reenable callback - on trigger disable must write disable registries as well - Modified trigger name length to 64 Eugen Hristev (3): ARM: dts: at91: sama5d2_xplained: enable ADTRG pin iio: adc: at91-sama5d2_adc: add hw trigger and buffer support iio: tools: generic_buffer: increase trigger length arch/arm/boot/dts/at91-sama5d2_xplained.dts | 16 +- drivers/iio/adc/at91-sama5d2_adc.c | 231 +++++++++++++++++++++++++++- tools/iio/iio_utils.h | 2 +- 3 files changed, 244 insertions(+), 5 deletions(-) -- 2.7.4 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
