The POWER block of the STM32MP1 integrates 3 fixed regulators with a ready
status bit for each one. The goal of this patchset is to add support those
regulators.

Pascal Paillet (2):
changes in v2:
* add COMPILE_TEST switch
* do not test ready in is_enabled() callback
* remove of_regulator_match
* change author

You should probably add a get_status() callback using this.
