> A 2ms delay on power down seems suspicious for a regulator. I'm not sure why this is required but if it is I suspect it's due to a large cap on the regulator output and light load rather than something that's always true for whatever regulator is providing the supply.

I wasn't suggesting to do the delay in the framework *itself*, rather in the
regulator driver and/or the board platform code which needs this delay.
