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 : For Tegra124, must contain "nvidia,tegra124-soctherm".
11 For Tegra132, must contain "nvidia,tegra132-soctherm".
12 For Tegra210, must contain "nvidia,tegra210-soctherm".
13 - reg : Should contain 1 entry:
14 - SOCTHERM register set
15 - interrupts : Defines the interrupt used by SOCTHERM
16 - clocks : Must contain an entry for each entry in clock-names.
17 See ../clocks/clock-bindings.txt for details.
18 - clock-names : Must include the following entries:
21 - resets : Must contain an entry for each entry in reset-names.
22 See ../reset/reset.txt for details.
23 - reset-names : Must include the following entries:
25 - #thermal-sensor-cells : Should be 1. See ./thermal.txt for a description
26 of this property. See <dt-bindings/thermal/tegra124-soctherm.h> for a
27 list of valid values when referring to thermal sensors.
