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

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.
