If these are not IDs, then you do not need them in the bindings." https://lore.kernel.org/all/59629ec1-cc0c-4c5a-87cc-ea30d64ec191@linaro.org/ As a consequence, as what you are describing there are hardware bits rather than IDs used by the driver, you can just use a numeric constant in device tree instead of adding dt-bindings header. Or change the driver so RST0_THERM_CTRL_SWRST could be defined as 0.

I usually comment this on new drivers which can be changed. Best regards, Krzysztof

I usually comment this on new drivers which can be changed. this is a new driver so i guess i should change this like daniel suggests. As i want to use this constant in dts and driver i would like keep it as binding in the reset header, but because i use it only as index in the infra_idx_map array its value does not need to have the value needed in hardware. i kept it same to not have different values and for ordering purposes (when the other possible resets are added). so the way starting at 0 will be the preferred one for me, is this ok? regards Frank
