Thanks for the changes, but that's not correct reason to remove DTS code. What kernel supports or not, should be irrelevant for the DTS. DTS for example is used in other projects - did you check if they have the same issues? Anyway, DTS describes the hardware, so how current kernel support defines what is and what is not in the hardware? Best regards, Krzysztof
