ADP1051: 6 PWM for I/O Voltage, I/O Current, Temperature
    ADP1055: 6 PWM for I/O Voltage, I/O Current, Power, Temperature
    LTP8800-1A/-2/-4A: 150A/135A/200A DC/DC µModule Regulator

The LTP8800 is a family of step-down μModule regulators that provides
microprocessor core voltage from 54V power distribution architecture.
LTP8800 features telemetry monitoring of input/output voltage, input
current, output power, and temperature over PMBus.

FYI:

The 'micro' symbol displays as a blank space in 'menuconfig' or 'nconfig'.
(It shows up correctly in gconfig and xconfig.)

This problem is not unique to this driver entry.
See https://lore.kernel.org/all/20231006202942.GA865945@bhelgaas/ from 2023.

AFAIK no one is working on this issue.
Feel free to change the help text or leave it...

If it's part of the commercial / official name, I would leave it.
The bug is not in the help text anyway.

Can we use small x to make it more visible that it's _not_ the part of the
name, but a glob-like placeholder?

Note, this can be dropped anyway in order to use PTR_IF() below, if required.

Ditto, are the fields not defined without the symbol?

Please, split this patch to at least two:
1) Introduce chip_info;
2) add new devices.

Please refrain from using device name wildcards, There is no guarantee that
all chips in the name range of ADP105[0-9] will have the same functionality.
Either name the chips, or say something like "The supported chips are ...".

As mentioned in my other reply, I'd rather not have a placeholder in the first
place.

Look into other drivers. That is how it is implemented there,
and not really the point. One has to know about an alternative to use it.

FWIW, PTR_IF() isn't widely used, and I for my part was not aware that
it exists.

They are, but they must be 0/NULL. PTR_IF() would be an alternative.
It is a bit odd to use it for a non-pointer, but it is type-agnostic,
so using it should be ok to avoid the #ifdefs. We should maybe adopt
that mechanism for other PMBus drivers.

That would really be "Use driver data to point to chip info".

I don't really care much about separating those two (after all, they are
related), but adding regulator support to the driver is a major change
and should be a separate patch. On top of that, it isn't even mentioned
in the patch description.

Thanks,

Yeah, it's a relatively new one...

I see, thanks for elaboration on all of this.

I agree on the title, what I meant is the rough description of what
should be done in the change.

Indeed, that's why I mentioned "at least" in the reply.
