This is an I2C driver, right?

I was under the impression that Linux could do auto-probing on I2C
devices?  Such that they do not require platform code or DT in order
to bind?

It's I2C driver. I'm not sure about auto-probing because something
should provide information about device to Linux. It's possible to
detect/scan whether there is device sitting on I2C address, but there is
no auto-discovery mechanism, AFAIK.

TPS80031 device will fail to bind to this driver because it explicitly
requires platform data which should be NULL if device is probed solely
by I2C ID.

Well, in general, it could be manually instantiated from userspace...

..but I agree in this case. The driver has this code:

        if (!pdata) {
                dev_err(&client->dev, "tps80031 requires platform data\n");
                return -EINVAL;
        }

and git grep shows no user having platform data.

Shouldn't 'drivers/regulator/tps80031-regulator.c' and
'./rtc/rtc-tps80031.c' be removed as well?

They are removed by the other 2 patches of this series [1].

This is a fair point.

I'll take the patch, thanks.
