> These property names are way too generic for device specific properties. There is zero description of what the h/w does and any of these child nodes to give any advice on direction. However, a node per register or register field is generally the wrong direction.

Thank you for your valued feedback. The goal I was trying to achieve here was making our programmable logic register driver interface in a generic way across multiple platforms based on inputs we provide with the .dts file for each platform. For instance if we want to read the fan 1 install status on platform X it would be reading bit 0x01 of byte 0x27 where as on platform Y it could be bit 0x02 of byte 0x16. Is there a format you would recommend that I can adhere too?

Thanks!
