Qualcomm Technologies, Inc. TSENS driver
|
||
|
|
|
||
|
|
Temperature sensor (TSENS) driver supports reading temperature from sensors
|
||
|
|
across the MSM. The driver defaults to support a 12 bit ADC.
|
||
|
|
|
||
|
|
The driver uses the Thermal sysfs framework to provide thermal
|
||
|
|
clients the ability to read from supported on-die temperature sensors,
|
||
|
|
set temperature thresholds for cool/warm thresholds and receive notification
|
||
|
|
on temperature threshold events.
|
||
|
|
|
||
|
|
TSENS node
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible : should be "qcom,msm8996-tsens" for 8996 TSENS driver.
|
||
|
|
should be "qcom,msm8953-tsens" for 8953 TSENS driver.
|
||
|
|
should be "qcom,msm8998-tsens" for 8998 TSENS driver.
|
||
|
|
should be "qcom,msmhamster-tsens" for hamster TSENS driver.
|
||
|
|
should be "qcom,sdm660-tsens" for 660 TSENS driver.
|
||
|
|
should be "qcom,sdm630-tsens" for 630 TSENS driver.
|
||
|
|
should be "qcom,sdm845-tsens" for SDM845 TSENS driver.
|
||
|
|
should be "qcom,tsens24xx" for 2.4 TSENS controller.
|
||
|
|
should be "qcom,msm8937-tsens" for 8937 TSENS driver.
|
||
|
|
should be "qcom,qcs405-tsens" for QCS405 TSENS driver.
|
||
|
|
should be "qcom,sm6150-tsens" for 6150 TSENS driver.
|
||
|
|
should be "qcom,mdm9607-tsens" for 9607 TSENS driver.
|
||
|
|
|
||
|
|
The compatible property is used to identify the respective controller to use
|
||
|
|
for the corresponding SoC.
|
||
|
|
- reg : offset and length of the TSENS registers with associated property in reg-names
|
||
|
|
as "tsens_srot_physical" for TSENS SROT physical address region. TSENS TM
|
||
|
|
physical address region as "tsens_tm_physical", and "tsens_eeprom_physical" for the
|
||
|
|
TSENS calibration fuse register region.
|
||
|
|
- reg-names : resource names used for the physical address of the TSENS
|
||
|
|
registers. Should be "tsens_srot_physical" for physical address of the TSENS
|
||
|
|
SROT region, "tsens_tm_physical" for physical address of the TM region and
|
||
|
|
"tsens_eeprom_physical" for the TSENS calibration fuse register region.
|
||
|
|
- interrupts : TSENS interrupt to notify Upper/Lower and Critical temperature threshold.
|
||
|
|
- interrupt-names: Should be "tsens-upper-lower" for temperature threshold.
|
||
|
|
Add "tsens-critical" for Critical temperature threshold notification
|
||
|
|
in addition to "tsens-upper-lower" for 8996 TSENS since
|
||
|
|
8996 supports Upper/Lower and Critical temperature threshold.
|
||
|
|
|
||
|

Example:
|
||
|
|
|
||
|
|
tsens@fc4a8000 {
|
||
|

compatible = "qcom,msm-tsens";
|

reg = <0xfc4a8000 0x10>,
|
||
|
|
<0xfc4b8000 0x1ff>;
|
||
|
|
reg-names = "tsens_srot_physical",
|
||
|
|
"tsens_tm_physical",
|
||
|
|
"tsens_eeprom_physical",
|
||
|
|
interrupts = <0 184 0>;
|
||
|
|
interrupt-names = "tsens-upper-lower";
|

};
