DTS is always independent thus usually put at the end of patchset or better separate. It is the first time I hear that DTS should be before driver. Best regards, Krzysztof

If that's not the case, I have no issues. I really doubt Rob ever suggested that. He probably suggested that bindings must come before user, but not the DTS. Best regards, Krzysztof

Besides, the flow in this patchset is very logical from the Linux POV 1. describe the hardware in bindings 2. implement the drivers, conforming to the description 3. describe the hardware in the device tree to ensure the (now existing) driver probes Konrad > > Best regards, > Krzysztof >
