Yes, this was discussed in v1.

Although they are related, these two devices do not use the same
protocol and regmap is not a good fit for ADS1X18. We need two different
SPI message structure for driving the two operating modes (direct,
buffer) and the trigger needs some special considerations because
ads1x18 share their drdy interrupt line with the MOSI pin.

We concluded merging the two drivers would be too messy as both
protocols would need a lot of unique code. Not to mention different
triggers, buffers, custom callbacks, etc.
