[PATCH v5 1/3] dt-bindings: hwmon/pmbus: Add Infineon xdp730

From: ASHISH YADAV

Date: Tue Jun 09 2026 - 03:29:03 EST


From: Ashish Yadav <ashish.yadav@xxxxxxxxxxxx>

Add documentation for the device tree binding of the XDP730 eFuse.
Rename node to efuse to accurately reflect its hardware function.

description: |
- The XDP720 is an eFuse with integrated current sensor and digital
- controller. It provides accurate system telemetry (V, I, P, T) and
- reports analog current at the IMON pin for post-processing.

- Datasheet:

+ Both parts share the same PMBus register map and direct-format
+ coefficients; they differ in the GIMON gain step exposed via the
+ TELEMETRY_AVG register (bit 10) and in the VDD_VIN pin number
+ (XDP720: pin 9, XDP730: pin 20).
