We do, otherwise dtc complains about defaults of #address-cells = 2 and #size-cells=1, and without empty "ranges" subnode's resources are not correctly translated. > > > + compatible = "samsung,exynos-srom"; > > + reg = <0x12250000 0x14>; > > + }; > > + > > pmu_system_controller: system-controller@10040000 { > > compatible = "samsung,exynos5410-pmu", "syscon"; > > reg = <0x10040000 0x5000>; > > @@ -133,6 +142,12 @@ > > <10 &gic 0 130 0>, > > <11 &gic 0 131 0>; > > }; > > + > > + arch_timer { > > + compatible = "arm,armv7-timer"; > > + clock-frequency = <24000000>; > > + }; > > + > > This change should not be part of this patch. Ooops, thank you very much, this should not have been here at all. This is a leftover from my experiments, i was tracing DT parsing code and added it just for test, to see why timer gets probed as a subnode. Just forgot to remove it afterwards and it slipped into the patch.
