It just has a few more drivers converted to use this approach like dsi/dpu and ufs. ufs demonstrates the case of having to handle multiple power domains, one of which is scalable. The patches are based on 5.1-rc1 and depend on some ufs fixes I posted earlier [2] and a DT patch to include the rpmpd header [3] [1] https://lkml.org/lkml/2019/1/28/2086 [2] https://lkml.org/lkml/2019/3/8/70 [3] https://lkml.org/lkml/2019/3/20/120 Rajendra Nayak (10): OPP: Make dev_pm_opp_set_rate() with freq=0 as valid 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 arm64: dts: sdm845: Add OPP table for all qup devices scsi: ufs: Add support to manage multiple power domains in ufshcd-pltfrm scsi: ufs: Add support for specifying OPP tables in DT arm64: dts: sdm845: Add ufs opps and power-domains drm/msm/dpu: Use OPP API to set clk/perf state drm/msm: dsi: Use OPP API to set clk/perf state arm64: dts: sdm845: Add DSI and MDP OPP tables and power-domains Stephen Boyd (1): OPP: Don't overwrite rounded clk rate arch/arm64/boot/dts/qcom/sdm845.dtsi | 194 +++++++++++++++++- drivers/gpu/drm/msm/disp/dpu1/dpu_core_perf.c | 7 +- drivers/gpu/drm/msm/disp/dpu1/dpu_kms.c | 9 + drivers/gpu/drm/msm/dsi/dsi.h | 2 + drivers/gpu/drm/msm/dsi/dsi_cfg.c | 4 +- drivers/gpu/drm/msm/dsi/dsi_host.c | 88 +++++++- drivers/opp/core.c | 26 ++- drivers/scsi/ufs/ufshcd-pltfrm.c | 52 ++++- drivers/scsi/ufs/ufshcd.c | 21 +- drivers/scsi/ufs/ufshcd.h | 3 + drivers/spi/spi-geni-qcom.c | 14 +- drivers/tty/serial/qcom_geni_serial.c | 15 +- 12 files changed, 406 insertions(+), 29 deletions(-)
