[PATCH 2/2] wifi: ath10k: snoc: Add VDD_SMPS regulator

[Konrad Dybcio]

At least SM6375 (bundled with soc_id 0x400e0000) and SM4350 (bundled
with unknown, probably the same) expect one more supply, called vdd-smps
downstream. It's set to 0.984V and connected to a - you guessed it - SMPS
regulator on PM6125. Add support for it.

The smps name sounds like a quick downstream hack and is probably
something more exquisite in reality.. Not something I know, though.

There is no explanation here, but looking at your driver change it
suggests name is not correct. You named it based on regulator (so the
provider), not the consumer.

Best regards,
Krzysztof

Right, I admit this could have been posted with an RFC tag.
Maybe Kalle knows more.

Yeah, it would be nice to have more than just one sentence in the commit
log.

Unfortunately not, but maybe Bjorn knows?
