I think I disagree. But I'm not familiar with syscon so I don't know. IIUC, syscon uses regmap to do mmio and this driver requires syscon to get at the regmap, and in the end this driver doesn't know anything about mmio. All it knows is syscon/regmap. If some warped syscon thing shows up that wraps something other than mmio in its regmap, this driver wouldn't care about it. And syscon is something that is also known in the DT world. Given that, I think everything in this driver should be named syscon and not mmio. Or?
