Clearly spec doesn't have that provision, I had raised this point in the past. Jens has similar concern and he did ask the same[1]. As I replied to him in that thread[2]. I am open to suggestion on how to auto-discover, currently as I see spec doesn't support it. -- Regards, Sudeep [1] https://lore.kernel.org/linux-arm-kernel/20201216134659.GA4146223@jade/ [2] https://lore.kernel.org/linux-arm-kernel/20210113092236.pnabzaufzuzwprmw@bogus/
