It doesn't match what Chromebooks do, so add a link to the Chromebook docs. Reported-by: Stephen Boyd Signed-off-by: Douglas Anderson Reviewed-by: Matthias Kaehlcke --- The link added here will (obviously) not function until the documentation patch makes it to mainline. Presumably folks who want to read it in the meantime can find it pretty easily. If there's a better way to link this then please let me know.
