Subject: [PATCH v2 0/3] iio: adc: Fix flags in sigma-delta drivers

From: Alexandru Tachici <alexandru.tachici@...log.com>

In Sigma-Delta devices the SDO line is also used as an interrupt.
Leaving IRQ on level instead of falling might trigger a sample read
when the IRQ is enabled, as the SDO line is already low. Not sure
if SDO line will always imediately go high in ad_sd_buffer_postenable
before the IRQ is enabled.

Some sigma-delta drivers use wrong irq_flags specified in the
ad_sigma_delta_info struct. Add the flags corresponding to the
interrupt type specified in the data-sheets of each chip.

Alexandru Tachici (3):
  iio: adc: ad7192: Add IRQ flag
  iio: adc: ad7780: Fix IRQ flag
  iio: adc: ad7793: Fix IRQ flag
