Subject: Meson GXL and Rockchip PHY based on same IP?

Meson GXL and Rockchip ethernet PHY drivers have quite something in common.
They share a number of non-standard registers, using the same bits
and same bank handling. This makes me think they they may be using
the same IP. However they have different quirk handling. But this
doesn't rule out that actually they would need the same quirk handling.
Eventually it might be possible to merge both drivers.
When working on the Meson GXL PHY driver, did you ever come across
this similarity?
