1 Tegra124 SOCTHERM thermal management system
3 The SOCTHERM IP block contains thermal sensors, support for polled
4 or interrupt-based thermal monitoring, CPU and GPU throttling based
5 on temperature trip points, and handling external overcurrent
6 notifications. It is also used to manage emergency shutdown in an
10 - compatible : "nvidia,tegra124-soctherm".
11 - reg : Should contain 1 entry:
12 - SOCTHERM register set
13 - interrupts : Defines the interrupt used by SOCTHERM
14 - clocks : Must contain an entry for each entry in clock-names.
15 See ../clocks/clock-bindings.txt for details.
16 - clock-names : Must include the following entries:
19 - resets : Must contain an entry for each entry in reset-names.
20 See ../reset/reset.txt for details.
21 - reset-names : Must include the following entries:
23 - #thermal-sensor-cells : Should be 1. See ./thermal.txt for a description
24 of this property. See <dt-bindings/thermal/tegra124-soctherm.h> for a
25 list of valid values when referring to thermal sensors.
