I came to the same conclusion that replacing gpio resets would probably be overkill, but I was only peripherally aware of the tegra reset controller. So a simple common struct and some oftree parsing code in drivers/reset that can replace both the proposed imx patch and what tegra_periph_reset_* do would be considered useful? > Unfortunately, I haven't had time to follow up on the proposal. regards Philipp
