2021-03-04	regulator: bd718x7, bd71828, Fix dvs voltage levels	Matti Vaittinen
	[ Upstream commit c294554111a835598b557db789d9ad2379b512a2 ] The ROHM BD718x7 and BD71828 drivers support setting HW state specific voltages from device-tree. This is used also by various in-tree DTS files. These drivers do incorrectly try to compose bit-map using enum values. By a chance this works for first two valid levels having values 1 and 2 - but setting values for the rest of the levels do indicate capability of setting values for first levels as well. Luckily the regulators which support setting values for SUSPEND/LPSR do usually also support setting values for RUN and IDLE too - thus this has not been such a fatal issue. Fix this by defining the old enum values as bits and fixing the parsing code. This allows keeping existing IC specific drivers intact and only slightly changing the rohm-regulator.c Fixes: 21b72156ede8b ("regulator: bd718x7: Split driver to common and bd718x7 specific parts") Signed-off-by: Matti Vaittinen <matti.vaittinen@fi.rohmeurope.com> Acked-by: Lee Jones <lee.jones@linaro.org> Link: https://lore.kernel.org/r/20210212080023.GA880728@localhost.localdomain Signed-off-by: Mark Brown <broonie@kernel.org> Signed-off-by: Sasha Levin <sashal@kernel.org>

	Few ROHM PMICs allow setting the voltage states for different system states like RUN, IDLE, SUSPEND and LPSR. States are then changed via SoC specific mechanisms. bd718x7 driver implemented device-tree parsing functions for these state specific voltages. The parsing functions can be re-used by other ROHM chip drivers like bd71828. Split the generic functions from bd718x7-regulator.c to rohm-regulator.c and export them for other modules to use.
