Subject: [PATCH] power: rpi-poe: Drop CURRENT_AVG as it is not
|
||
|
|
hardware averaged
|
||
|
|
|
||
|
|
As documented the _AVG parameters are meant to be hardware
|
||
|
|
averaged, but the implementation for the PoE+ HAT was done in
|
||
|
|
software in the firmware.
|
||
|
|
|
||
|
|
Drop the property.
