And it's max current which is the h/w property where as anything less is just software configuration (IOW, doesn't belong in DT).

I was following the work on it, but it seems to have halted after September. > > > + qcom,tx-driver-strength: > > + description: PSGMII/QSGMII TX driver strength control. > > + $ref: /schemas/types.yaml#/definitions/uint32 > > + enum: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12] > > Please use the actual values here, and have the driver convert to the > value poked into the register.

I am using defines in dt-binding includes for this one as it makes the values humanly readable in DT as these configure the amplitude and bias current for power saving. > > Andrew

Nothing to do with LEDs. The description needs improving. Yes, this is used to set the PSGMII/QSMII SerDes TX driver strength. It has nothing to do with LEDs. I agree that the description is a bit confusing, I will try to make it a bit clearer. > > Andrew
