[PATCH net-next] net: phy: add support for TI DP83561-SP phy

From: hnagalla
Date: Tue Nov 16 2021 - 05:21:21 EST


From: Hari Nagalla <hnagalla@xxxxxx>

Add support for the TI DP83561-SP Gigabit ethernet phy device.

The dp83561-sp is a high reliability gigabit ethernet PHY designed for
the high-radiation environment of space. It interfaces directly to
twisted pair media through an external transformer. The device
interfaces directly to the MAC layer through Reduced GMII (RGMII) and MII.

DP83867, DP83869 and DP83561-SP, all these parts support 1000Base-T/
100Base-TX/ and 10Base-Te standards and have similar register map for
the core functionality.

The data sheet for this part is at https://www.ti.com/product/DP83561-SP
