I suppose this argument applies here as well:

"IDs should start from 0 or 1 and increment by 1. If these are not IDs,
then you do not need them in the bindings."

https://lore.kernel.org/all/59629ec1-cc0c-4c5a-87cc-ea30d64ec191@xxxxxxxxxx/

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.
