We would like to add support for GPIO-controlled power load switches (for example: the tps229* series from Texas Instruments). We use this chip to power-cycle devices whose power consumption is measured using baylibre-acme probes thus we need a way to control them from user space.
I initially submitted a series adding this support via the iio framework, but it was decided that iio is not the right interface for that. This series extends the regulator core to support regulators controlled from user space and reuses the fixed regulator driver to support gpio power switches.
