Is there a max value you can define? Sorry not sure I follow, to clarify you mean drop uint32, if so which type to use u8? I can use u8 as max wont be beyond 255. Yes I will define min as well max values too. > Otherwise, up to 2^32 - 1 is valid. I see one more warning given by your bot which I am able to reproduce as well: Documentation/devicetree/bindings/dma/qcom,gpi.example.dt.yaml: example-0: dma-controller@800000:reg:0: [0, 8388608, 0, 393216] is too long So to fix this I added the #address-cells and #size-cells #address-cells = <2>; #size-cells = <2>; reg = <0x0 0x00800000 0x0 0x60000>; But I am getting the warning, what am I doing incorrect -- ~Vinod
