Signed-off-by: Arnd Bergmann --- If this looks ok, I'd apply it directly to the fixes branch for 4.15, as the warning is one that was introduced in this release. --- arch/arm64/boot/dts/mediatek/mt8173.dtsi | 2 ++ 1 file changed, 2 insertions(+) diff --git a/arch/arm64/boot/dts/mediatek/mt8173.dtsi b/arch/arm64/boot/dts/mediatek/mt8173.dtsi index b477ad790071..9fbe4705ee88 100644 --- a/arch/arm64/boot/dts/mediatek/mt8173.dtsi +++ b/arch/arm64/boot/dts/mediatek/mt8173.dtsi @@ -155,6 +155,7 @@ reg = <0x000>; enable-method = "psci"; cpu-idle-states = <&CPU_SLEEP_0>; + #cooling-cells = <2>; clocks = <&infracfg CLK_INFRA_CA53SEL>, <&apmixedsys CLK_APMIXED_MAINPLL>; clock-names = "cpu", "intermediate"; @@ -179,6 +180,7 @@ reg = <0x100>; enable-method = "psci"; cpu-idle-states = <&CPU_SLEEP_0>; + #cooling-cells = <2>; clocks = <&infracfg CLK_INFRA_CA57SEL>, <&apmixedsys CLK_APMIXED_MAINPLL>; clock-names = "cpu", "intermediate"; -- 2.9.0
