Subject: [PATCH/RFC 07/19] OMAP3: voltage: add scalable flag to
voltagedomain
Add a 'bool scalable' flag to the struct powerdomain and set it for
I suppose you meant "struct voltagedomain".
yes
But shouldn't this flag be part of PMIC struct?
Voltage scalability depends on the kind of VDD supply from PMIC. So even
if OMAP supports voltage scaling, we may not be able to scale the voltage
if PMIC does not support it.
That's a good point. Probably I can drop this flag and just use the
existence of the various fields of the voltage domain (pmic, vc, vp,
etc.) to determine if the voltdm can scale.
Mmm, the scalability is still a characteristic of the OMAP voltage
domain. Some are scalable with a supported range of voltage, some are not.
So that information is relevant in the voltage domain. Then the
regulator framework will have as well some information about the range
that should match what OMAP is able to do.
