Meson GXL and Rockchip PHY based on same IP?

Meson GXL and Rockchip PHY based on same IP?

[Heiner Kallweit]

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?

You made me curious and I found the following public Microchip
LAN83C185 datasheet: [0]
Page 27 has a "SMI REGISTER MAPPING" which matches the definitions in
meson-gxl.c.
Also on page 33 the interrupt source bits are a 100% match with the
INTSRC_* marcos in meson-gxl.c

Whether this means that:
- Amlogic SoCs embed a LAN83C185
- LAN83C185 is based on the same IP core (possibly not even designed
by Amlogic or SMSC)
- the SMI interface design is something that one hardware engineer
brought from one company to another
- ...something else
is something I can't tell


Best regards,
Martin

I believe it to be the case, yes.

However, the version of the IP could be different.
The integration the SoC vendor did is very likely to be different too.

I'd be in favor of keeping things the way they are now.
I don't think merging the drivers now is really worth the effort.
With the uncertainty there is around SoC integration, It could bring more
problems that it solves down the line.

It has been pointed out that they have different quirks. It would be
good to check if any of the quirks in one should be applied to the
other.
