Same went for some other devices, like the > ad40{02,06,10}. Yes, that's correct. Some chips only vary by name and max sample rate which boils down to only having a different dev_name in the driver. Can those have grouped compatible strings? dt_binding_check fails if curly brackets are used. properties: compatible: enum: - adi,ad402{0,1,2} The groups of similar chips are: AD4020/AD4021/AD4022 AD4003/AD4007/AD4011 AD4002/AD4006/AD4010 AD4001/AD4005 AD4000/AD4004/AD4008 Thanks, Marcelo > > Thanks, > Conor.
