Oleksandr Shamray	525dd5aed6	hwmon: (pmbus/mp2888) Fix sensors readouts for MPS Multi-phase mp2888 controller ... Fix scale factors for reading MPS Multi-phase mp2888 controller. Fixed sensors: - PIN/POUT: based on vendor documentation, set bscale factor 0.5W/LSB - IOUT: based on vendor documentation, set scale factor 0.25 A/LSB Fixes: e4db7719d0 ("hwmon: (pmbus) Add support for MPS Multi-phase mp2888 controller") Signed-off-by: Oleksandr Shamray <oleksandrs@nvidia.com> Reviewed-by: Vadim Pasternak <vadimp@nvidia.com> Link: https://lore.kernel.org/r/20220929121642.63051-1-oleksandrs@nvidia.com Signed-off-by: Guenter Roeck <linux@roeck-us.net>	2022-10-02 08:07:11 -07:00
Vadim Pasternak	e4db7719d0	hwmon: (pmbus) Add support for MPS Multi-phase mp2888 controller ... Add support for mp2888 device from Monolithic Power Systems, Inc. (MPS) vendor. This is a digital, multi-phase, pulse-width modulation controller. This device supports: - One power rail. - Programmable Multi-Phase up to 10 Phases. - PWM-VID Interface - One pages 0 for telemetry. - Programmable pins for PMBus Address. - Built-In EEPROM to Store Custom Configurations. - Can configured VOUT readout in direct or VID format and allows setting of different formats on rails 1 and 2. For VID the following protocols are available: VR13 mode with 5-mV DAC; VR13 mode with 10-mV DAC, IMVP9 mode with 5-mV DAC.
