Sorry if I have not been clear enough, but what I meant was that we could probably create a 5v regulator in sunxi-common-regulators. It will probably be useful for other boards in the same case, so we'd better put it there, instead of redefining it everywhere (just like we did for reg_vcc3v and reg_vcc3v3) Maxime -- Maxime Ripard, Free Electrons Embedded Linux, Kernel and Android engineering http://free-electrons.com
