[PATCH v3 0/4] Add DT support for J721E CPSW9G and J7200 CPSW5G

[Siddharth Vadapalli]

Hello,

This series adds the device-tree nodes for the CPSW9G instance of CPSW
Ethernet Switch on TI's J721E SoC and the CPSW5G instance of CPSW
Ethernet Switch on TI's J7200 SoC. Additionally, overlays are also added
to individually enable CPSW9G on J721E SoC and CPSW5G on J7200 SoC in
QSGMII mode with the Add-On J7 QUAD Port Ethernet expansion QSGMII
daughtercard.

This series combines the v2 series for J721E CPSW9G at:
https://lore.kernel.org/r/20230310103504.731845-1-s-vadapalli@xxxxxx/
and the v1 series for J7200 CPSW5G at:
https://lore.kernel.org/r/20230310101407.722334-1-s-vadapalli@xxxxxx/

The suggestions for the v2 series for J721E are implemented for the J7200
series as well in this patch series.

Changes from v2 for J721E CPSW9G series:
1. Rename the overlay k3-j721e-quad-port-eth-exp.dtso as
   k3-j721e-evm-quad-port-eth-exp.dtso.
2. Update arch/arm64/boot/dts/ti/Makefile to build k3-j721e-evm.dtb as the
   result of applying k3-j721e-evm-quad-port-eth-exp.dtbo to
   k3-j721e-common-proc-board.dtb.
3. Use the newer "&{/} {" style instead of the "fragments" style in
   k3-j721e-evm-quad-port-eth-exp.dtso.
4. Move the "mdio0_pins_default" pinctrl from cpsw0 node into the
   "cpsw9g_mdio" node.
5. Disable individual "cpsw0_port" nodes in the main.dtsi file, enabling
   only the required nodes in the overlay.
6. Disable the "cpsw9g_mdio" node in the main.dtsi file.

Changes from v1 for J721E CPSW9G series:
1. Rename node name "mdio_pins_default" to "mdio0-pins-default", since
   node names shouldn't contain underscores.
2. Change node label "mdio_pins_default" to "mdio0_pins_default".

Changes from v1 for J7200 CPSW5G series:
1. Rename the overlay k3-j7200-quad-port-eth-exp.dtso as
   k3-j7200-evm-quad-port-eth-exp.dtso.
2. Update arch/arm64/boot/dts/ti/Makefile to build k3-j7200-evm.dtb as the
   result of applying k3-j7200-evm-quad-port-eth-exp.dtbo to
   k3-j7200-common-proc-board.dtb.
3. Use the newer "&{/} {" style instead of the "fragments" style in
   k3-j7200-evm-quad-port-eth-exp.dtso.
4. Move the "mdio0_pins_default" pinctrl from cpsw0 node into the
   "cpsw5g_mdio" node.
5. Disable individual "cpsw0_port" nodes in the main.dtsi file, enabling
   only the required nodes in the overlay.
6. Disable the "cpsw5g_mdio" node in the main.dtsi file.
