Hi,
These patches add support for the Infineon XDP730 Digital eFuse Controller
by updating the existing XDP720 driver.
The XDP720 and XDP730 are PMBus-compliant digital eFuse controllers
with an integrated current sensor.They provide accurate system
telemetry (V, I, P, T) and report analog current at the IMON pin for
post-processing.
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).
The Current and Power measurement depends on the RIMON and GIMON values.
The GIMON (microA/A) depends on the 10th bit of TELEMETRY_AVG PMBUS Register.
The value of RIMON (kohm) can be provided by the user through device tree using
infineon,rimon-micro-ohms property.
