Add initial support for the Texas Instruments TPS25990 eFuse. This adds the basic PMBUS telemetry support for the device. From Karol Przybylski: The tps25990_read_word_data function contains a block of unreachable code caused by the syntactic structure in the PMBUS_VIRT_READ_IIN_MAX case. Specifically, the return TPS25990_READ_IIN_PEAK; statement immediately exits the function, making the next lines unreachable. This patch removes the return statement, leaving the expected handling.

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.

2021-04-20hwmon: Add driver for fsp-3y PSUs and PDUsVáclav Kubernát
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.

2019-06-23hwmon: (pmbus) Add Infineon IRPS5401 driverRobert Hancock
Add a driver to support the Infineon IRPS5401 PMIC. This chip has 5 pages corresponding to 4 switching outputs and one linear (LDO) output. The switching and LDO outputs have slightly different supported parameters. Signed-off-by: Robert Hancock <hancock@sedsystems.ca> Signed-off-by: Guenter Roeck <linux@roeck-us.net>

2019-04-15hwmon: (pmbus/ir38064) Add driver for Infineon IR38064 Voltage RegulatorMaxim Sloyko
Add the pmbus driver for the Infineon ir38064 voltage regulator. VOUT_MODE is not supported by the device. The driver fakes linear16 mode with exponent value -8. The device supports VOUT_PEAK, IOUT_PEAK, and TEMPERATURE_PEAK, however this driver does not enable them.
