You should also mention that it's a bodge because you're permanently
enabling the regulators rather than controlling them from the mmc-pwrseq
stuff.

I would like to see a proper implementation rather than a bodge -
especially one which permanently enables the oscillator regulator,
thus having the oscillator output trying to drive a device which is
powered down, which will forward-bias the ESD diodes... which is not
a particularly nice thing to do.

So really that's a NAK on this.  Please do the job properly.
