> I don't think DT place is to describe register or memory layout, with some exceptions like MTD partitions or nvmem cells. Basically you are representing here a device register map inside DT, just because it is a CPLD. > Every regular multi-functional device handles its register map in the driver itself and uses Linux framework to expose the internals. CPLD should not be different, except that is programmable. Hi Krzysztof, Thank you for your time and feedback. We are looking for a place to describe differences within our CPLD implementation due to our memory mapping not being consistent. The idea we are pursuing is to use the device tree to serve as an input to Linux to prevent driver code fragmentation from multiple platforms needing their own specific offsets. If this is not acceptable to do through the device tree, should we rely on having an include file for each platform instead? Thanks, -Nick Hawkins
