I'd like an exynos Ack though before applying. It's correct, at least with ARMv7 Exynos datasheets The few ARMv8 Exynos chips are silent about the voltage levels. The Exynos 7 DTS board in mainline kernel does not have regulator but it looks clearly like mistake. I think they behave the same, so for Exynos: Reviewed-by: Krzysztof Kozlowski <krzk@xxxxxxxxxx> Best regards, Krzysztof > thanks, > > Jonathan > >
