First question is why not to use the regmap API (I have heard it has
gained support of 17 bit)?

Initially that was the plan, but after this patch:
https://github.com/torvalds/linux/commit/4191f19792bf91267835eb090d970e9cd6277a65
the custom write formats for regmap allow the read only via cached registers.

Therefore, I preferred using spi transfers for write/read to/from the device.

Not sure I follow you. That patch is upstream. Does it prevent you
from switching to regmap SPI API?

+        depends on COMMON_CLK

Is it mandatory for any function inside the device?

Yes. It will serve as LO input to the device.

But can the device work without it (with limited functionality)?
