Hi, @karthikgowda6!
I’ve tried to find a driver for this IC, but, apparently, there is no driver for this specific model. So, it won’t be possible to add an SPI node or driver to our device tree.
I saw that you asked another question, so I’ll keep the answers here since the topic is related.
Another option in your case is using SPIDEV to communicate with the DAC from user space. Please, refer to this article to find out how it is done, and feel free to ask if you have any doubts.
Best regards.
