I'm not sure if that would be flexible enough to meet the requirement:
power for each OPP might be different in one board vs. other board.
Don't DT files overload values from board files all the time ? Why wouldn't the
same apply for OPP table as well ?
In that SoC and family of the boards, there are no such examples.
Here is one I think.
arch/arm64/boot/dts/freescale/imx8mq-librem5-r3.dts
It used to be popular in arm32 boards, but I'm not sure nowadays.
I think it is still common, not with OPPs though.
AFAIK the OPP definition is more SoC specific.
This isn't about OPP definition as well, but just that if DT allows you to
override or not. I think it will.
Redefining the whole OPP table, when the freq, voltage, interconnect,
and other old entries don't change isn't too messy?
I think you misunderstood what I said. The common part of the OPP table should
stay in the central .dtsi file. The dts files though, should just add the power
specific values to the existing OPP table.
OK, I misunderstood that. If that is possible than it would
be great. I'm assuming you are taking about OPP v2. I can relax the
requirement that I need to provide this DT-EM for arm32, since they
have a legacy OPP v1.
So we might have an entry similar that interconnect for the
bandwidth, but for us it would be 'opp-power-uw'?
Let me have a look about some examples how that could be just
added/extended in the opp table but from board file.
If you have some handy link, I would be grateful.
