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.
