[PATCH 0/3] net: stmmac: Detect PHY location with phy-is-integrated

[PATCH 0/3] net: stmmac: Detect PHY location with phy-is-integrated

[Corentin Labbe]

Hello

The current way to find if the phy is internal is to compare DT phy-mode
and emac_variant/internal_phy.
But it will negate a possible future SoC where an external PHY use the
same phy mode than the internal one.

This patchs series adds a new way to find if the PHY is internal, via
the phy-is-integrated DT property.

The first and third patch should go via the net tree.
the second via the sunxi tree.

Thanks
Regards

[PATCH 1/3] Documentation: bindings: Add documentation for phy-is-integrated

[Corentin Labbe]

This patch adds documentation for phy-is-integrated, a boolean property
for PHY which permit to know if the PHY is integrated in the SoC.

For example, Allwinner H3 embeds an internal PHY but still permit to
connect an external PHY.
Since it is possible in theory to have the same PHY model both internal
and external, the only way to detect the location of the PHY is via this property.

You also need to "delete" this property at the board level for
any board that has the external PHY at address <1>. Otherwise
they will stop working. This is due to the internal and external
PHYs having the same path and node name in the device tree, so
they are effectively the same node.

That is just the label. The label plays no part in device tree merging. The path

    /soc/ethernet at 1c30000/mdio/ethernet-phy at 1

is the same. You can look under

    /proc/device-tree/soc/ethernet at 1c30000/mdio

on the OrangePI Plus 2E or any other H3 board that uses an
external PHY at address 1.

That is just the label. The label plays no part in device tree merging. The path

    /soc/ethernet@1c30000/mdio/ethernet-phy@1

is the same. You can look under

    /proc/device-tree/soc/ethernet@1c30000/mdio

on the OrangePI Plus 2E or any other H3 board that uses an
external PHY at address 1.

You are not getting me. The fact that the two seemingly separate
nodes are merged together means, whatever properties you put in
the internal PHY node, also affect the external PHY node. Once
compiled, they are the SAME node.

So why not changing the internal node name from ethernet-phy to integrated-phy ?

Hello Rob, florian, mark

Adding a delete property on all external ethernet-phy at 1 is a bit overkill, and I dont like the idea that nodes are merged.
What do you think about other possible solutions:
- Using integrated-phy at 1 for the integrated PHY node name
- Using a fake address like 31 (see patch below)

If you have any other solution...

Subject: [PATCH] ARM: sun8i: sunxi-h3-h5: Prevent merge of external and
 integrated PHY

Actually, some external and integrated PHY are merged due to same dtnode
name "ethernet-phy at 1".

This is problematic when we will want to use the phy-is-integrated
property. (Need to delete it on all external PHY node)

An easy solution is to set integrated PHY nodeaddresss at a fake one
that would never be used.
Since board makers currently only provides PHY at addresses 1 and 7,
we will use 31.

This is not exactly up to you that's just how DTC works.

That might be okay although you are using now a seemingly non-standard unit name.

>- Using a fake address like 31 (see patch below)

You could also drop the address part in the unit name although we'd probably get a DTC warning for that.

I suspect both of your solutions and what I mentioned above will be producing DTC warnings to some extent... Rob what do you think?

This is not exactly up to you that's just how DTC works.

That might be okay although you are using now a seemingly non-standard unit name.

You could also drop the address part in the unit name although we'd probably get a DTC warning for that.

I suspect both of your solutions and what I mentioned above will be producing DTC warnings to some extent... Rob what do you think?

I think I found an easier solution, putting phy-is-integrated on board DT nodes only.

If you have 2 devices at the same address, then there is some mux in the 
middle. Describe that and you problems should be solved. The internal 
phy is always there, so it should be able to always be in the DT.

[PATCH 3/3] net: stmmac: dwmac-sun8i: choose internal PHY via phy-is-integrated

[Corentin Labbe]

The current way to find if the phy is internal is to compare DT phy-mode
and emac_variant/internal_phy.
But it will negate a possible future SoC where an external PHY use the
same phy mode than the internal one.

This patch adds a new way to find if the PHY is internal, via
the phy-is-integrated property.

Since the internal_phy variable does not need anymore to contain the xMII mode
used by the internal PHY, it is still used for knowing the presence of an
internal PHY, so it is modified to a boolean soc_has_internal_phy.
