I personally wasn't focusing on (and didn't test much) videocc but pulled it along for the ride. Most of the work in this series deals with the fact that the parenting info for these clock controllers was in a bad shape. It looks like it was half transitioned from the old way of doing things (relying on global names) to the new way of doing things (putting the linkage in the device tree). This should fully transition us. As part of this transition I update the sdm845.dtsi file to specify the info as per the new way of doing things. Although I've now put the linkage info in the sdm845.dtsi file, though, I haven't updated the sdm845 clock drivers in Linux so they still work via the global name matching. It's left as an exercise to the reader to update the sdm845 clock drivers in Linux. This series passes these things for me on linux-next (next-20200129) after picking the recent gcc fix I posted [1]: for f in \ Documentation/devicetree/bindings/clock/qcom,msm8998-gpucc.yaml \ Documentation/devicetree/bindings/clock/qcom,sc7180-dispcc.yaml \ Documentation/devicetree/bindings/clock/qcom,sc7180-gpucc.yaml \ Documentation/devicetree/bindings/clock/qcom,sc7180-videocc.yaml \ Documentation/devicetree/bindings/clock/qcom,sdm845-dispcc.yaml \ Documentation/devicetree/bindings/clock/qcom,sdm845-gpucc.yaml \ Documentation/devicetree/bindings/clock/qcom,sdm845-videocc.yaml; do \ ARCH=arm64 make dtbs_check DT_SCHEMA_FILES=$f; \ done I also tried this: # Delete broken yaml: rm Documentation/devicetree/bindings/pci/intel-gw-pcie.yaml ARCH=arm64 make dt_binding_check | grep 'clock/qcom' ...and that didn't seem to indicate problems. I also tried this (make sure you don't run w/ -j64 or diff is hard): # Delete broken yaml: rm Documentation/devicetree/bindings/pci/intel-gw-pcie.yaml git checkout beforeMyCode ARCH=arm64 make dt_binding_check > old.txt 2>&1 git checkout myCode ARCH=arm64 make dt_binding_check > new.txt 2>&1 diff old.txt new.txt ...and that didn't seem to indicate problems. I have confirmed that (with extra patches) the display/gpu come up on sc7180 and sdm845-cheza. You can find the top of my downstream tree at: https://crrev.com/c/2017976/4 I have confirmed that sdm845-cheza display / GPU come up atop next-20200129, which is what this series is posted against. Compared to v2, this series has quite a few changes. Mostly it's: - Always split into multiple files (Stephen). - Use internal names, not purist names (Taniya). - I realized that I forgot to update the sc7180 video clock controller driver in v2. - A few other misc cleanups / fixes, see each patch for details. It feels like with this many patches there's very little chance I didn't do something stupid like make a tpyo or a paste-o paste-o, though I tried to cross-check as much as I could. I apologize in advance for the stupid things I did that I should have known better about.
