2023-03-02drivers/net/phy/m88e1512: Add a way to set output impedance manuallyMario Scheithauer
This patch provides the functionality to set the RGMII output impedance manually. To ensure that no race condition occurs, the driver strength values for PMOS and NMOS should be written to the RGMII output impedance calibration override register first and then the force bit should be enabled with a second write to this register.

2023-03-02drivers/net/phy/m88e1512: Switch the page back to 0 only onceMario Scheithauer
When the configuration of Marvell PHY 88E1512 is finished, then switch the page back to 0 only once at the end of the Init function.

2022-11-24drivers/net/phy/m88e1512: Add downshift enableMario Scheithauer
This patch provides the functionality to enable downshift on Marvell PHY. By setting a downshift counter, the PHY is correspondingly often attempted to establish Gigabit link before the PHY downshifts to the next highest speed. The range is limited to 8 trials. To activate downshift, a software reset must follow to take effect.

2022-11-24drivers/net/phy/m88e1512: Add new driver for Marvell PHY 88E1512Mario Scheithauer
This driver enables the usage of an external Marvell PHY 88E1512 which should be connected to a SOC internal MAC controller. In a first step it is only the framework of the driver. Functionality will follow with a second patch.
