+ channel@0 {

+ ti,n-factor = /bits/ 8 <(-10)>;
+ label = "local";
+ };
Setting the n-factor for the local channel is not supported, so we
should remove this attribute for this example and move it to another
channel.
Here is the output on a hardware test:
[165599.122883] tmp464 16-0049: n-factor can't be set for internal channel
[165599.123833] tmp464: probe of 16-0049 failed with error -22
+
+ channel@1 {
+ reg = <0x1>;
+ ti,n-factor = /bits/ 8 <0x0>;
+ label = "somelabel";
+ };
No particular issue when defining a property for channel that is not
internal during driver probe.
+
+ channel@2 {
+ reg = <0x2>;
+ status = "disabled";
+ };
Works as expected on target:
root@fct-0a:/sys/class/hwmon/hwmon2 >cat temp3_input
cat: temp3_input: No data available
Best regards,
Agathe.
