Merge branch 'net-ftgmac100-add-soc-reset-support-for-rmii-mode'
Jacky Chou says:
====================
net: ftgmac100: Add SoC reset support for RMII mode
This patch series adds support for an optional reset line to the
ftgmac100 ethernet controller, as used on Aspeed SoCs. On these SoCs,
the internal MAC reset is not sufficient to reset the RMII interface.
By providing a SoC-level reset via the device tree "resets" property,
the driver can properly reset both the MAC and RMII logic, ensuring
correct operation in RMII mode.
The series includes:
- Device tree binding update to document the new "resets" property.
- Addition of MAC1/2/3/4 reset definitions for AST2600.
- Driver changes to assert/deassert the reset line as needed.
This improves reliability and initialization of the MAC in RMII mode
on Aspeed platforms.
