Yes, it's certainly something we should be doing. Most Tegra boards will
only have all the regulators defined in device tree for the first time
in kernel 3.7, and so we've been holding off making any of the client
nodes use regulators because of that. Now that we have all the
regulators defined, I do hope we will quickly move to using them for
SDHCI. Pavan (now CC'd) will hopefully be doing this.
