Why increase to 2? Per the doc, the last one is dma reset, currently dw I3C driver doesn't support dma. And increasing it to 3 is still dt compatible. Maybe I misunderstood something. what's more, I don't have platforms with all 3 resets to test and verify. If dt maintainers prefer 3 in one step, I will sent out a follow-up patch.
