No, neither explained, nor correct. See DTS coding style.

Please use name for all fixed regulators which matches current format
recommendation: 'regulator-[0-9]v[0-9]'

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/ tree/Documentation/devicetree/bindings/regulator/fixed-regulator.yaml? h=v6.11-rc1#n46

'regulator-[0-9]v[0-9]' is preferred, but 'regulator-[0-9a-z-]+' is also permitted, right?

i.e. regulator-vcc3v3_pcie2x1l2 should be regulator-vcc3v3-pcie2x1l2


Or, should we revert below patch and use 'regulator-[0-9]v[0-9]'?

 https://lore.kernel.org/ all/0ae40493-93e9-40cd-9ca9-990ae064f21a@xxxxxxxxx/

Is 'regulator-0v0' valid?
Is 'regulator-12v0' invalid?

How should we handle multiple 1v8/3v3/5v0 regulators?

Are examples in fixed-regulator.yaml valid?
'regulator-name' should be '[0-9]v[0-9]' even if there is same name?

Best regards,
