| Subject: arm64: dts: add #cooling-cells to CPU nodes |
| |
| From: Arnd Bergmann <arnd@arndb.de> |
| |
| commit acbf76ee05067c3942852019993f7beb69a0f45f upstream. |
| |
| dtc complains about the lack of #coolin-cells properties for the |
| CPU nodes that are referred to as "cooling-device": |
| |
| arch/arm64/boot/dts/mediatek/mt8173-evb.dtb: Warning (cooling_device_property): Missing property '#cooling-cells' in node /cpus/cpu@0 or bad phandle (referred from /thermal-zones/cpu_thermal/cooling-maps/map@0:cooling-device[0]) |
| arch/arm64/boot/dts/mediatek/mt8173-evb.dtb: Warning (cooling_device_property): Missing property '#cooling-cells' in node /cpus/cpu@100 or bad phandle (referred from /thermal-zones/cpu_thermal/cooling-maps/map@1:cooling-device[0]) |
| |
| Apparently this property must be '<2>' to match the binding. |
