[PATCH v2 0/3] Add support to PHY GMII SEL for J721e CPSW9G QSGMII

[PATCH v2 0/3] Add support to PHY GMII SEL for J721e CPSW9G QSGMII

[Siddharth Vadapalli]

Add compatible for J721e CPSW9G, which contains 8 external ports and 1
internal host port.

Update existing approach of using compatible to differentiate between
devices that support QSGMII mode and those that don't. The new
approach involves storing the number of qsgmii main ports for the device
in the num_qsgmii_main_ports member of the "struct phy_gmii_sel_soc_data".
This approach makes it scalable for newer devices.

=========
Changelog
=========
v1 -> v2:
1. Drop all patches corresponding to SGMII mode. This is done since I do
   not have a method to test SGMII in the standard mode which uses an
   SGMII PHY. The previous series used SGMII in a fixed-link mode,
   bypassing the SGMII PHY. I will post the SGMII patches in a future
   series after testing them.
2. Update description for the property "ti,qsgmii-main-ports", to describe
   it in a unified way across the compatibles.
3. Add minItems, maxItems, and items at the top, where the property
   "ti,qsgmii-main-ports" is first defined. Modify them later
   appropriately, based on the compatible.
4. Update the method to fetch the property "ti,qsgmii-main-ports" from the
   device-tree, to make it scalable.
5. Use dev_err() when the value(s) provided in the device-tree for the
   property "ti,qsgmii-main-ports" is/are invalid.

[PATCH v2 2/3] phy: ti: gmii-sel: Update methods for fetching and using qsgmii main port

[Siddharth Vadapalli]

The number of QSGMII main ports are specific to the device. TI's J7200 for
which the QSGMII main port property is fetched from the device-tree has
only one QSGMII main port. However, devices like TI's J721e support up to
two QSGMII main ports. Thus, the existing methods for fetching and using
the QSGMII main port are not scalable.

Update the existing methods for handling the QSGMII main ports and its
associated requirements to make it scalable for future devices.

[PATCH v2 2/3] phy: ti: gmii-sel: Update methods for fetching and using qsgmii main port

[Siddharth Vadapalli]

The number of QSGMII main ports are specific to the device. TI's J7200 for
which the QSGMII main port property is fetched from the device-tree has
only one QSGMII main port. However, devices like TI's J721e support up to
two QSGMII main ports. Thus, the existing methods for fetching and using
the QSGMII main port are not scalable.

Update the existing methods for handling the QSGMII main ports and its
associated requirements to make it scalable for future devices.

[PATCH v2 3/3] phy: ti: gmii-sel: Add support for CPSW9G GMII SEL in J721e

[Siddharth Vadapalli]

Each of the CPSW9G ports in J721e support additional modes like QSGMII.
Add a new compatible for J721e to support the additional modes.

In TI's J721e, each of the CPSW9G ethernet interfaces can act as a
QSGMII main or QSGMII-SUB port. The QSGMII main interface is responsible
for performing auto-negotiation between the MAC and the PHY while the rest
of the interfaces are designated as QSGMII-SUB interfaces, indicating that
they will not be taking part in the auto-negotiation process.

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/patch/

This check can fail if there are any dependencies. The base for a patch
series is generally the most recent rc1.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit.

I will fix the errors in the v3 series and ensure that there are no
errors or warnings with dt_binding_check, using the updated dt-schema
and yamllint.
