It might be interesting to be explicit about what happens if "regulator-allowed-modes" doesn't include the mode that was listed as "regulator-initial-mode". Does that mean that there's no way to get back to "regulator-initial-mode" after it's been changed once, or is it an error to not include the initial mode in the set of allowed modes? I'm not 100% sure if going to such detail is necessary though. Thus, feel free to add: Reviewed-by: Douglas Anderson <dianders@chromium.org>

Add a common device tree property for regulator nodes to support the specification of allowed operating modes. Signed-off-by: David Collins <collinsd@codeaurora.org> --- Documentation/devicetree/bindings/regulator/regulator.txt | 5 +++++ 1 file changed, 5 insertions(+)
