2021-02-12regulator: bd718x7, bd71828, Fix dvs voltage levelsMatti Vaittinen1-8/+6
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>

2020-01-24regulator: bd718x7: Split driver to common and bd718x7 specific partsMatti Vaittinen1-0/+66
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.

BD71828GW is a single-chip power management IC for battery-powered portable devices. The IC integrates 7 buck converters, 7 LDOs, and a 1500 mA single-cell linear charger. Also included is a Coulomb counter, a real-time clock (RTC), 3 GPO/regulator control pins, HALL input and a 32.768 kHz clock gate. Add MFD core driver providing interrupt controller facilities and i2c access to sub device drivers.

2020-01-24mfd: Rohm PMICs: Use platform_device_id to match MFD sub-devicesMatti Vaittinen1-2/+1
Thanks to Stephen Boyd I today learned we can use platform_device_id to do device and module matching for MFD sub-devices! Do device matching using the platform_device_id instead of using explicit module_aliases to load modules and custom parent-data field to do module loading and sub-device matching.

2019-06-27mfd: regulator: clk: Split rohm-bd718x7.hMatti Vaittinen1-0/+20
Split the bd718x7.h to ROHM common and bd718x7 specific parts so that we do not need to add same things in every new ROHM PMIC header. Please note that this change requires changes also in bd718x7 sub-device drivers for regulators and clk.
