Re: [PATCH v6 0/6] DVFS for IO devices on sdm845 and sc7180

What is the plan for landing these, it seems not all must/should
go through the QCOM tree.

My guesses:

tty: serial: qcom_geni_serial: Use OPP API to set clk/perf state
spi: spi-geni-qcom: Use OPP API to set clk/perf state
  QCOM tree due to shared dependency on change in include/linux/qcom-geni-se.h

drm/msm/dpu: Use OPP API to set clk/perf state
drm/msm: dsi: Use OPP API to set clk/perf state
  drm/msm tree

media: venus: core: Add support for opp tables/perf voting
  venus tree

spi: spi-qcom-qspi: Use OPP API to set clk/perf state
  SPI tree


Does this make sense or are there any dependencies I'm missing?

Thanks

Matthias
