OMAP SOCs have a standard set of tuples consisting of frequency and
voltage pairs that the device will support per voltage domain. These
are called Operating Performance Points or OPPs.
(...)
This introduces a common handling OPP mechanism accross all OMAPs.
As a start this is used for OMAP3.
OPPs are a generic concept, it's in silicon construction textbooks and all.
Should this code not be made generic instead? You wouldn't make
regulators or even DMA platform-specific these days, so why should
OPPs be?
As far as I see this patch :
hwmod[1] which is omap specific which inturn depends on omap_device. -
this impacts opp_add function in the opp layer.
