regulator: introduce min_dropout_uV (5abe4f22) · Commits · 戴 / test

Many voltage Regulators need a input voltage that is higher than the output voltage. Allow to specify a minimum dropout voltage which will be used later to find the best input voltage for regulators. [Changed uv to uV for consistency and legibility -- broonie] Signed-off-by:
