[ti-dac5571] Checking compatibility of TI DAC with kernel driver

[Akash Borde]

Hi,

I'd like to see if the TI DAC8563 is potentially compatible with this existing device driver in the main branch of the kernel.

This is the part I'm evaluating for my board: https://www.ti.com/lit/ds/symlink/dac8563.pdf 
Here is the most similar kernel driver I could find: https://github.com/torvalds/linux/blob/master/drivers/iio/dac/ti-dac5571.c

I see very similar DACs in the compatible list of this driver, but not the exact part number family that I'm looking for.
Is there a way to verify a DAC or family of DACs' compatibility with existing drivers?

Thanks!

Sadly best bet is to open the datasheets side by side and verify if the
devices are compatible in all software visible ways.

It's a pain to do but only way to know if it will continue to be compatible
in the future if new driver features are added.
