TPS80031 driver was upstreamed back in 2013 and never got a user. I noticed
that driver is abandoned while was about to write a patch to switch it to a
new power-off API (that I'm working on). Driver requires platform data that
nobody provides. Instead of changing the dead code, let's remove it.

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?

This is a fair point.
I'll take the patch, thanks.

Thanks!
[2/3] regulator: tps80031: Remove driver
commit: d7477e646291b2dcdd5521cf926cd390ddd6a7c1
All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying
to this mail.
Thanks,
Mark
