This patchset aims to add support for the Internal RMII Ethernet PHY of the
Amlogic Meson GXL S905X SoC on the Amlogic P212 Reference board.
The Internal PHY needs a specific config then acts as a generic PHY.

The Amlogic Meson GXL/GXM families embeds an internal RMII Ethernet PHY.
The PHY acts as a generic PHY but needs a slight configuration right
before it's configuration.

We really should create a uclass for PHY drivers before adding any
more of these.

Hi Simon,
Sure, this would indeed be necessary, but is it necessary to wait for the uclass to merge mode PHYs ?

Well, this isn't going in before the next release (along with all of the
other amlogic stuff, which looks good otherwise btw). So, do you have
time to take a pass at a uclass?

Hi Tom, Simon,
I can give a try, but with my limited uclass/dm knowledge, it will only be basic and will some review.
Should the plan be to introduce DM support for net PHY subsystem, then introduce this meson GXL phy as first implementation ?
Should I remove support for non-dm PHY drivers and probing when DM is enabled ?
