These should map to existing opp entries.
I ended up doing the interconnect driver that maps a clock to the
interconnect. Then I can use it in the cpu opp tables.
Can you point us at what it is you are proposing ?
https://patchwork.kernel.org/project/linux-arm-msm/patch/20230120061417.2623751-9-dmitry.baryshkov@xxxxxxxxxx/
Is there no driver code too ?
There are two parts, one is the 'CBF clock' driver, which just provides
a clock, another part actually connects the clock and interconnect.
Initially I implemented it as a part of the CBF driver (see
https://patchwork.kernel.org/project/linux-arm-msm/patch/20230120061417.2623751-5-dmitry.baryshkov@xxxxxxxxxx/),
next revision will move the interconnect part to drivers/interconnect.
