I really don't know what the stuff collected here is called.

## that tm thing with "@"
|
|
|
|
Someone really needs to tell me how those things are called, not knowing the right term makes it all much more complicated.
|
|
|
|
Also, why are there multiple adc_tm@3400 in the downstream Device Tree..?
|
|
|
|
Example:
|
|
|
|
```
|
|
adc_tm@3400 {
|
|
compatible = "qcom,adc-tm7";
|
|
reg = <0x3400>;
|
|
interrupts = <0x06 0x34 0x00 0x01>;
|
|
interrupt-names = "thr-int-en";
|
|
#address-cells = <0x01>;
|
|
#size-cells = <0x00>;
|
|
#thermal-sensor-cells = <0x01>;
|
|
io-channels = <0x7f 0x644>;
|
|
phandle = <0x5b>;
|
|
|
|
xo_therm {
|
|
reg = <0x644>;
|
|
qcom,ratiometric;
|
|
qcom,hw-settle-time = <0xc8>;
|
|
};
|
|
};
|
|
```
|
|
|
|
and
|
|
|
|
```
|
|
adc_tm@3400 {
|
|
compatible = "qcom,adc-tm5-iio";
|
|
reg = <0x3400 0x100>;
|
|
#thermal-sensor-cells = <0x01>;
|
|
#address-cells = <0x01>;
|
|
#size-cells = <0x00>;
|
|
io-channels = <0x7c 0x4e 0x7c 0x53>;
|
|
phandle = <0x59>;
|
|
|
|
msm_therm {
|
|
reg = <0x4e>;
|
|
qcom,ratiometric;
|
|
qcom,hw-settle-time = <0xc8>;
|
|
};
|
|
|
|
rfc_cam_therm {
|
|
reg = <0x53>;
|
|
qcom,ratiometric;
|
|
qcom,hw-settle-time = <0xc8>;
|
|
};
|
|
};
|
|
};
|
|
```
|
|
|
|
The `compatible` string differs. My understanding is that this defines what something is, but how can it be two things at the same time..?
|
|
|
|
| which tm thing (compatible) | what is listed there |
|
|
| -------------- | -------------------- |
|
|
| adc_tm@3400 (qcom,adc-tm7) | xo_therm |
|
|
| adc_tm@3400 (qcom,adc-tm5-iio) | msm_therm, rfc_cam_therm |
|
|
| adc_tm@3500 (qcom,adc-tm5) | charger_skin_therm, conn_therm |
|
|
| adc_tm@3500 (qcom,adc-tm5) | pa_therm1, pa_therm0, rear_cam_flash_therm, quiet_therm |
|
