hwmon/pmbus: (isl68137) Add support for raa229141

2025-11-12T20:13:41Z

The RAA229141A is a digital dual output multiphase (X+Y ≤ 12) PWM controller designed to be compliant with Intel VR13, VR13.HC, VR14 and VR14.Cloud specifications, targeting VCORE and auxiliary rails. The RAA229141A supports the Intel SVID interface along with PMBus V1.3 specifications, making it ideal for controlling the microprocessor core and system rails in Intel VR13, VR13.HC, VR14 and VR14.Cloud platforms.

module: Convert symbol namespace to string literal

2024-12-02T19:34:44Z

Clean up the existing export namespace code along the same lines of commit 33def8498fdd ("treewide: Convert macro and uses of __section(foo) to __section("foo")") and for the same reason, it is not desired for the namespace argument to be a macro expansion itself.

hwmon: (pmbus/isl68137) add support for voltage divider on Vout

2024-11-13T20:08:07Z

Some applications require Vout to be higher than the detectable voltage range of the Vsense pin for a given rail. In such applications, a voltage divider may be placed between Vout and the Vsense pin, but this results in erroneous telemetry being read back from the part. This change adds support for a voltage divider to be defined in the devicetree for a (or multiple) specific rail(s) for a supported digital multiphase device and for the applicable Vout telemetry to be scaled based on the voltage divider configuration. This change copies the implementation of the vout-voltage-divider devicetree property defined in the maxim,max20730 bindings schema since it is the best fit for the use case of scaling hwmon PMBus telemetry. The generic voltage-divider property used by many iio drivers was determined to be a poor fit because that schema is tied directly to iio and the isl68137 driver is not an iio driver.

hwmon: Switch i2c drivers back to use .probe()

2023-06-08T13:41:17Z

After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new() call-back type"), all drivers being converted to .probe_new() and then 03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert back to (the new) .probe() to be able to eventually drop .probe_new() from struct i2c_driver.

hwmon: (pmbus/isl68137) remove READ_TEMPERATURE_3 for RAA228228

2021-05-16T23:00:56Z

The initial version of the RAA228228 datasheet claimed that the device supported READ_TEMPERATURE_3 but not READ_TEMPERATURE_1. It has since been discovered that the datasheet was incorrect. The RAA228228 does support READ_TEMPERATURE_1 but does not support READ_TEMPERATURE_3.
