net: phy: motorcomm: Support YT8531S PHY in YT6801 Ethernet controller

2026-01-13T03:20:56+00:00

YT6801's internal PHY is confirmed as a GMII-capable variant of YT8531S by a previous series[1] and reading PHY ID. Add support for PHY_INTERFACE_MODE_GMII for YT8531S to allow the Ethernet driver to reuse the PHY code for its internal PHY.

net: phy: motorcomm: Add pad drive strength cfg support

2023-07-24T09:36:45+00:00

The motorcomm phy (YT8531) supports the ability to adjust the drive strength of the rx_clk/rx_data, and the default strength may not be suitable for all boards. So add configurable options to better match the boards.(e.g. StarFive VisionFive 2) When we configure the drive strength, we need to read the current LDO voltage value to ensure that it is a legal value at that LDO voltage.
