Would be good to mention why you are treating hamoa-iot-evk differently. > Signed-off-by: Dipa Ramesh Mantre <[email protected]> > Reviewed-by: Dmitry Baryshkov <[email protected]> > Signed-off-by: Gaurav Kohli <[email protected]> > --- > arch/arm64/boot/dts/qcom/hamoa-iot-evk.dts | 32 +++++++++++++++ > arch/arm64/boot/dts/qcom/hamoa.dtsi | 63 > ++++++++++++++++++++++++++++++ > 2 files changed, 95 insertions(+) > > diff --git a/arch/arm64/boot/dts/qcom/hamoa-iot-evk.dts > b/arch/arm64/boot/dts/qcom/hamoa-iot-evk.dts > index 9fa86bb6438e..a146be1cb5fb 100644 > --- a/arch/arm64/boot/dts/qcom/hamoa-iot-evk.dts > +++ b/arch/arm64/boot/dts/qcom/hamoa-iot-evk.dts > @@ -1684,4 +1684,36 @@ trip-point0 { > }; > }; > }; > + > + nsp0-thermal { > + trips { > + trip-point1 { > + temperature = <105000>; > + }; > + }; > + }; > + > + nsp1-thermal { > + trips { > + trip-point1 { > + temperature = <105000>; > + }; > + }; > + }; > + > + nsp2-thermal { > + trips { > + trip-point1 { > + temperature = <105000>; > + }; > + }; > + }; > + > + nsp3-thermal { > + trips { > + trip-point1 { > + temperature = <105000>; > + }; > + }; > + }; > }; Please avoid overriding node values like this... One quick rename of one of the involved nodes and this will be silently broken without compile error. Nowadays dtbs_check will *probably* catch these, but if you override values using the label reference you would notice it immediately when compiling. All those nodes already have a label you can use: &nsp0_alert0 { temperature = <105000>; }; &nsp1_alert0 { temperature = <105000>; }; If the same pattern is already used for other thermal overrides in hamoa-iot-evk.dts, it would be good to prepend a patch to fix those too.
