hwmon: (pmbus) Add Delta AHE-50DC fan control module driver

2021-12-26T23:02:06Z

This device is an integrated module of the Delta AHE-50DC Open19 power shelf. I haven't been able to procure any proper documentation for it, but it seems to be a (somewhat minimally) PMBus-compliant device. It provides four fan speeds, four temperatures (three standard and one manufacturer-specific via a virtual second page), and a vin reading.

hwmon: (pmbus) Add support for MPS Multi-phase mp2888 controller

2021-06-17T11:21:45Z

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.

hwmon: (pmbus) Add pmbus driver for MAX15301

2021-04-20T13:50:14Z

Add pmbus driver support for Maxim MAX15301 InTune Automatically Compensated Digital PoL Controller with Driver and PMBus Telemetry Even though the specification does not specifically mention it, extensive empirical testing has revealed that auto-detection of limit-registers will fail in a random fashion unless the delay parameter is set to above about 80us. The default delay is set to 100us to include some safety margin. This patch is tested on a Flex BMR461 converter module.

hwmon: Add driver for fsp-3y PSUs and PDUs

2021-04-20T13:50:14Z

This patch adds support for these devices: - YH-5151E - the PDU - YM-2151E - the PSU The device datasheet says that the devices support PMBus 1.2, but in my testing, a lot of the commands aren't supported and if they are, they sometimes behave strangely or inconsistently. For example, writes to the PAGE command requires using PEC, otherwise the write won't work and the page won't switch, even though, the standard says that PEC is optional. On the other hand, writes to SMBALERT don't require PEC. Because of this, the driver is mostly reverse engineered with the help of a tool called pmbus_peek written by David Brownell (and later adopted by my colleague Jan Kundrát). The device also has some sort of a timing issue when switching pages, which is explained further in the code. Because of this, the driver support is limited. It exposes only the values that have been tested to work correctly.
