[PATCH v2 0/6] Add SGMII support for MAIN CPSW on TI's J7200 SoC

[Siddharth Vadapalli]

Hello,

This series adds support for SGMII mode to the CPSW driver to enable the
functionality on TI's J7200 SoC.

Supporting SGMII mode also requires changes to the WIZ driver which acts
as a wrapper for the SerDes used by the CPSW MAC to transmit data to the
Ethernet PHY daughtercard mounted on the I2C GPIO Expander 2 connector on
the J7200 EVM.

Powering on and resetting the Ethernet PHY requires MDIO support which
is added to the CPSW driver.

For supporting DMA transactions from the MAIN CPSW instance to the A72
Host on J7200 SoC, the corresponding PSI-L endpoint information is
added for the J721E SoC, which is applicable to J7200 SoC as well.

The SGMII daughtercard used for testing SGMII mode has TI's DP83869 PHY.
Thus, enable the config for DP83869 driver functionality. Also, enable
GPIO HOG config.

Regards,
Siddharth.

v1:
https://patchwork.ozlabs.org/project/uboot/list/?series=362969&state=%2A&archive=both
Changes since v1:
- Add checks in the am65-cpsw-nuss.c driver for the DM_GPIO config being enabled:
  if (IS_ENABLED(CONFIG_DM_GPIO))
  to fix build errors for SoCs which don't have DM_GPIO config enabled.
- Rebase series on commit 7755b22007 of u-boot master.

**NOTE**: This series is based on top of commit:
7755b22007 Merge tag 'x86-pull-20230801' of https://source.denx.de/u-boot/custodians/u-boot-x86
