Hmm, how do you envision not repeating the same bits in a separate binding? Does it help if I convert this to YAML first without a ti, prefix in the file name? The usage philosophy definitely was to use a <soc-compatible> followed by the <generic-compatible>. This is how all of our reset nodes were added as well. Looks like Andrew may have misinterpreted your comment [1] during the original binding and changed "syscon-reset" to "ti,syscon-reset" in the final version [2]. regards Suman [1] https://lore.kernel.org/patchwork/comment/876688/ [2] https://lore.kernel.org/patchwork/patch/693172/ > > Best Regards > Crystal >> >>> - #reset-cells : Should be 1.
