Are there any other dependencies for this series? I tried applying
this on top of Georgi's series on v5.7-rc3. Patch 12 didn't apply
cleanly and needed a manual fixup for the include change.

Compilation failed with:
Error: /home/amit/work/sources/worktree-review-pipeline/arch/arm64/boot/dts/qcom/sc7180.dtsi:101.30-31
syntax error
FATAL ERROR: Unable to parse input tree

I've been squinting at the offending lines with no success:
                        interconnects = <&gem_noc MASTER_APPSS_PROC
&mc_virt SLAVE_EBI1>,
                                        <&osm_l3 MASTER_OSM_L3_APPS
&osm_l3 SLAVE_OSM_L3>;
