Question @ Mark/Liam:
Shouldn't we use the generic 'regulator-coupled-with' property
instead of 'ti,multi-phase-id' ?
My understanding was that this was a hardware configuration where
two regulators operate as one with only one set of registers used
for configuration.
Your understanding was correct.
I am in charge of upstreaming dt-bindings and maintainers
pointed out the similarity between 'multi-phase' and 'coupled'
regulator concepts. Does 'regulator-coupled-with' mean that
outputs of buck converters are combined ? If so, this generic
property should replace our specific 'ti,multi-phase-id' prop,
I guess.
No, coupled regulators are regulators where the voltages can vary
but there's a constraint that their configurations need to be
related somehow, for example they must be within 200mV of each
other or something like that.
OK, thank you for this explanation.
So, we keep 'ti,multi-phase-id' property.
