Corresponding devicetree binding are also removed. If it has benefits, why remove the support for this? -Daniel > > Details for DPU driver upstreaming: > https://lists.freedesktop.org/archives/freedreno/2018-February/001678.html > > Changes in v2: > - Remove last reference to dpu_power_rsc_update > - Add DPU PATCH tag for better filtering > - Rebase on tip of for-next-staging > > Rajesh Yadav (2): > dt-bindings: msm/disp: Remove DPU RSC device bindings > drm/msm: Remove RSC support from DPU driver > > .../devicetree/bindings/display/msm/dpu-rsc.txt | 96 -- > drivers/gpu/drm/msm/disp/dpu1/dpu_core_perf.c | 130 +- > drivers/gpu/drm/msm/disp/dpu1/dpu_core_perf.h | 6 - > drivers/gpu/drm/msm/disp/dpu1/dpu_crtc.c | 14 - > drivers/gpu/drm/msm/disp/dpu1/dpu_crtc.h | 9 +- > drivers/gpu/drm/msm/disp/dpu1/dpu_encoder.c | 242 +--- > drivers/gpu/drm/msm/disp/dpu1/dpu_encoder.h | 7 - > drivers/gpu/drm/msm/disp/dpu1/dpu_encoder_phys.h | 1 - > drivers/gpu/drm/msm/disp/dpu1/dpu_hw_top.c | 20 +- > drivers/gpu/drm/msm/disp/dpu1/dpu_hw_top.h | 3 - > drivers/gpu/drm/msm/dpu_dbg.c | 27 - > drivers/gpu/drm/msm/dpu_dbg.h | 10 - > drivers/gpu/drm/msm/dpu_power_handle.c | 73 +- > drivers/gpu/drm/msm/dpu_power_handle.h | 4 - > drivers/gpu/drm/msm/dpu_rsc.c | 1367 -------------------- > drivers/gpu/drm/msm/dpu_rsc_hw.c | 818 ------------ > drivers/gpu/drm/msm/dpu_rsc_priv.h | 191 --- > include/linux/dpu_rsc.h | 302 ----- > 18 files changed, 42 insertions(+), 3278 deletions(-) > delete mode 100644 Documentation/devicetree/bindings/display/msm/dpu-rsc.txt > delete mode 100644 drivers/gpu/drm/msm/dpu_rsc.c > delete mode 100644 drivers/gpu/drm/msm/dpu_rsc_hw.c > delete mode 100644 drivers/gpu/drm/msm/dpu_rsc_priv.h > delete mode 100644 include/linux/dpu_rsc.h > > -- > The Qualcomm Innovation Center, Inc. is a member of the Code Aurora Forum, > a Linux Foundation Collaborative Project > > _______________________________________________ > dri-devel mailing list > dri-devel@xxxxxxxxxxxxxxxxxxxxx > https://lists.freedesktop.org/mailman/listinfo/dri-devel -- Daniel Vetter Software Engineer, Intel Corporation http://blog.ffwll.ch _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
