Anyone can implement the newer V2 version (basically whoever wants something more than a simple freq/volt pair). So arm32 SoC's that want to use the DT-EM thing, should migrate to opp-v2, we can't support that with opp-v1. > So we might have an entry similar that interconnect for the > bandwidth, but for us it would be 'opp-power-uw'? I will rather say similar to opp-microvolt or opp-microamp, so it better be opp-microwatt. > 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. The file I provided earlier: arch/arm64/boot/dts/freescale/imx8mq-librem5-r3.dts This is updating opp-microvolt property of a single OPP node in the whole table. Pretty much like this only. -- viresh
