regulator: Add soft start support
Some regulators support a "soft start" feature where the voltage ramps up slowly when the regulator is enabled. Add an op (set_soft_start) and a DT property + constraint to support this. Signed-off-by: Stephen Boyd <sboyd@codeaurora.org> Signed-off-by: Mark Brown <broonie@kernel.org>
