[PATCH 1/2] dt-bindings: phy: qcom,ipq8074-qmp-pcie: Document the ipq5210 QMP PCIe PHY

[Varadarajan Narayanan]

Document the PCIe phy on the ipq5210 platform using the ipq9574 bindings
as a fallback, since the PCIe phy on the ipq5210 is similar to ipq9574.

dt-bindings: phy: qcom,ipq8074-qmp-pcie: Document the ipq5210 QMP PCIe PHY

This commit documents the ipq5210 QMP PCIe PHY. It aims to use the ipq9574
bindings as a fallback, as the hardware is similar.

The commit message states the intent to document the IPQ5210 PHY "using the
ipq9574 bindings as a fallback". Does adding the compatible string to this
standalone enum allow device trees to omit the fallback and still pass
validation?

Since this is inside a oneOf block, a device tree could specify just this
string without the ipq9574 fallback, defeating the intended requirement.

The gen3x2 variant added here correctly enforces the fallback because it
was not added to the standalone enum above.

Does this new table duplicate the existing ipq6018_pcie_tx_tbl? Could we
reuse the existing table instead of creating a redundant copy?

Is it possible this is an exact duplicate of ipq6018_pcie_pcs_tbl?

Could this table be entirely replaced by ipq8074_pcie_gen3_tx_tbl?

Also, does the name ipq9574_pcie_tx_tbl accurately reflect its usage? It
seems to be used exclusively by the newly added ipq5210_gen3x1_pciephy_cfg,
while the actual IPQ9574 configurations retain their use of the ipq8074 table.

If ipq9574_pcie_tx_tbl is identical to ipq8074_pcie_gen3_tx_tbl, should
this reference the existing ipq8074_pcie_gen3_tx_tbl instead?

Similarly, could these point to ipq6018_pcie_tx_tbl and
ipq6018_pcie_pcs_tbl respectively?

I don't understand that. You claim to use fallback only because
they are "similar", which is clearly incomplete reason. Many things are
similar. And your driver explicitly does not use fallback, which MUST be
explained WHY.

So it is or it is not compatible with 9574?

Sorry. It is compatible with 9574. Will fix this and post a new version.
