Merge branch '2023-08-15-add-SGMII-support-for-TI-j7200' into next
To quote the author:
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.
