You should be using your SoC compatible strings here. OPP compatible
property isn't supposed to be (mis)used for this purpose.
Referring to my comments in patch 1, what if we end up changing the bindings
based on DT maintainer comments? We will have these compatible strings, and
at that point is it acceptable to match against them? Or is it still better
to match to SoC compatibles? I think it makes sense to just probe against
these.
But even then I think these are not correct. You should have added a
single compatible string: operating-points-v2-ti-cpu.
As the properties will stay the same across machines. And then you
need to use SoC strings here.
Are you opposed to moving _of_get_opp_desc_node from
drivers/base/power/opp/opp.h to include/linux/pm_opp.h and renaming it
appropriately?
If I move the ti properties out of the cpu node, as discussed in patch 1
of this series, and into the operating-points-v2 table, I need a way to
get the operating-points-v2 device node and I think it makes sense to
reuse this as it is what the opp framework uses internally to parse the
phandle to the opp table.
