Subject: [PATCH 0/2] net: phy: dp83867: add numeric impedance DT property

Introduce a new way to set the output impedance over device tree.
So far it is possible to pass the value either over an nvmem
cell or to set the min and max booleans over device tree.

In our use case we want to be able to set the impedance over
device tree but the boolean values are not the right fit to 
provide best signal integrity for the hardware.
