[PATCH v2 0/3] iio: adc: Fix flags in sigma-delta drivers
From: alexandru.tachici

From: Alexandru Tachici <alexandru.tachici@xxxxxxxxxx>
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.
