- soctherm-reg

- interrupts : Defines the interrupt used by SOCTHERM
- clocks : Must contain an entry for each entry in clock-names.
See ../clocks/clock-bindings.txt for details.
@ -25,17 +31,45 @@ Required properties :
- #thermal-sensor-cells : Should be 1. See ./thermal.txt for a description
of this property. See <dt-bindings/thermal/tegra124-soctherm.h> for a
list of valid values when referring to thermal sensors.
- throttle-cfgs: A sub-node which is a container of configuration for each
hardware throttle events. These events can be set as cooling devices.
* throttle events: Sub-nodes must be named as "light" or "heavy".
Properties:
- nvidia,priority: Each throttles has its own throttle settings, so the
SW need to set priorities for various throttle, the HW arbiter can select
the final throttle settings.
Bigger value indicates higher priority, In general, higher priority
translates to lower target frequency. SW needs to ensure that critical
thermal alarms are given higher priority, and ensure that there is
no race if priority of two vectors is set to the same value.
The range of this value is 1~100.
- nvidia,cpu-throt-percent: This property is for Tegra124 and Tegra210.
It is the throttling depth of pulse skippers, it's the percentage
throttling.
- nvidia,cpu-throt-level: This property is only for Tegra132, it is the
level of pulse skippers, which used to throttle clock frequencies. It
indicates cpu clock throttling depth, and the depth can be programmed.
Must set as following values:
TEGRA_SOCTHERM_THROT_LEVEL_LOW, TEGRA_SOCTHERM_THROT_LEVEL_MED
TEGRA_SOCTHERM_THROT_LEVEL_HIGH, TEGRA_SOCTHERM_THROT_LEVEL_NONE
- #cooling-cells: Should be 1. This cooling device only support on/off state.
See ./thermal.txt for a description of this property.
Note:
- the "critical" type trip points will be set to SOC_THERM hardware as the
shut down temperature. Once the temperature of this thermal zone is higher
than it, the system will be shutdown or reset by hardware.
- the "hot" type trip points will be set to SOC_THERM hardware as the throttle
temperature. Once the the temperature of this thermal zone is higher
than it, it will trigger the HW throttle event.
