It is a no-op. Just mention in this commit msg, that both resets and reset-names are coming from snps,dwmac so they can be removed from top-level entirely. Best regards, Krzysztof

This has been discussed during v2 review [1], where I also provided the rational behind not updating reset-names. So the code was not deleted, but moved under an if clause.

I kept two sets of changes which were not directly related into separate patches, so I'm going to squash them in v5. Thanks, Cristian

The Synopsys DesignWare MAC found on StarFive JH7100 SoC is mostly similar to the newer JH7110, but it requires only two interrupts and a single reset line, which is 'ahb' instead of the commonly used 'stmmaceth'. Since the common binding 'snps,dwmac' allows selecting 'ahb' only in conjunction with 'stmmaceth', extend the logic to also permit exclusive usage of the 'ahb' reset name. This ensures the following use cases are supported: JH7110: reset-names = "stmmaceth", "ahb"; JH7100: reset-names = "ahb"; other: reset-names = "stmmaceth"; Also note the need to use a different dwmac fallback, as v5.20 applies to JH7110 only, while JH7100 relies on v3.7x.
