[PATCH 01/10] dt-bindings: thermal: tegra: Document throttle temperature

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Thierry Reding <treding@xxxxxxxxxx>

Each throttling configuration needs to specify the temperature threshold
at which it should start throttling. Previously this was tied to a given
trip point as a cooling device and used the temperature specified for
that trip point. This doesn't work well because the throttling mechanism
is not a cooling device in the traditional sense.

Instead, allow device trees to specify the throttle temperature in the
throttle configuration directly so that the throttle doesn't need to be
exposed as a cooling device.
