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.

Datasheets:

 - XDP730: https://www.infineon.com/assets/row/public/documents/24/49/infineon-xdp730-001-datasheet-en.pdf

Reordering include files and adding the regulator include
is an unrelated change and would need to be done in a separate patch.

Is this preference or needed ? Either case, it is an unrelated change.

Another unrelated change.

Please, if you want to clean up the driver, that is fine, but please do it
with separate patches. It is ok to make a simple cleanup change as part of
a patch like this, but it needs to be mentioned in the commit message.
But this goes beyond "simple". The patch

- Reorders include files to alphabetic order
- Adds the missing regulator include
- Declares XDP720_DEFAULT_RIMON as unsigned constant
- Changes error return to dev_err_probe()
- (unnecessarily) changes the rimon/gimon declaration order

in addition to adding support for the new chip. This is just too much.
Please split that out.

Thanks,
Guenter
