If you're introducing a regulator that doesn't exist in reality just to be able to share a GPIO line that is wired to several real regulators, then it _is_ ficticious. You're not describing the hardware, you're describing something else to work around the shortcomings of the implementation that can't cope with how stuff is wired up in the real world. You're making the DT description fit the software implementation, rather than the software implementation fit the real world hardware. Having a single GPIO that controls multiple separate regulators which have entirely separate supplies of their own is very common in electronics. -- RMK's Patch system: http://www.armlinux.org.uk/developer/patches/ FTTC broadband for 0.8mile line in suburbia: sync at 12.1Mbps down 622kbps up According to speedtest.net: 11.9Mbps down 500kbps up
