Hi Igor
You mean your firmware is blocking you from accessing these PHY
registers?

I think the HWMON maintainer prefers they come from the hardware. You
are also going to get odd results, when the provisioning data for the
PHY is different to what you hard code in the driver. The PHY shuts
down to protect itself, but your hard coded values indicate everything
should be O.K.
I would suggest you stick with the current patch, until you can add
more features to the firmware to allow access to these registers.
