What if it is both? When do you need this? Seems like you'd always want to monitor both directions to undo any action done on rising temp. Unless you want a hysteresis, but this doesn't seem like the best way to implement that. > > Signed-off-by: Thara Gopinath <thara.gopinath@xxxxxxxxxx> > --- > Documentation/devicetree/bindings/thermal/thermal.txt | 8 ++++++++ > 1 file changed, 8 insertions(+) > > diff --git a/Documentation/devicetree/bindings/thermal/thermal.txt b/Documentation/devicetree/bindings/thermal/thermal.txt > index ca14ba9..849a2a9 100644 > --- a/Documentation/devicetree/bindings/thermal/thermal.txt > +++ b/Documentation/devicetree/bindings/thermal/thermal.txt > @@ -90,6 +90,14 @@ Required properties: > "critical": Hardware not reliable. > Type: string > > +Optional property: > +- monitor-falling: Indicate whether the system action is kick > + Type: boolean started when the temperature falls below or rises > + above the trip temperature level indicated in > + "temperature".If true, the trip point is monitored > + for falling temperature else the trip point is > + monitored for rising temperature. > + > * Cooling device maps > > The cooling device maps node is a node to describe how cooling devices > -- > 2.1.4 >
