Is the Marvell phy driver (drivers/net/phy/marvell.c that supports the Marvell Alaska 88E1512 Phy used on any of the QorIQ products and tested?

1. What driver is used for the LS1043ARDB EC1 RGMII PHY addr: 1 and EC2 RGMII PHY addr: 2? 

2. What is the speed for both EC1 RGMII and EC2 RGMII?

3. What changes will be required if we change from physical address 1 and 2 to address 0.  Intending to use Marvell Alaska 88E1512 Phy physical 1 with a 1 Gbe RGMII Address =0 and Phy 2 100 MbE SGMII Address = 0 and trying to get a feel of changes required to support the address change if any.

4. Is the Marvell phy driver (drivers/net/phy/marvell.c) that supports the Marvell Alaska 88E1512 Phy used on any of the QorIQ products and tested?

1. See Ethernet drivers using the following path in NXP SDK Linux kernel:

/QorIQ-SDK-V2.0-20160527-yocto/build_ls1043ardb/tmp/work/ls1043ardb-fsl-linux/linux-qoriq/4.1-r0/git/drivers/net/ethernet/freescale

2. Look at the Table 33-2 of the LS1043a Reference Manual. This table shows that LS1043a RGMII speed is 1Gbps.

3. Change .dts file for your setting.

Have a great day,

You mention the .dts file will need to change, which specific .dts file should change for the 88E1512? I only see support for the 88E1510 in drivers/net/phy/marvell.c:

                .phy_id = MARVELL_PHY_ID_88E1510,
                .phy_id_mask = MARVELL_PHY_ID_MASK,
                .name = "Marvell 88E1510",
                .features = PHY_GBIT_FEATURES,
                .flags = PHY_HAS_INTERRUPT,
                .config_aneg = &m88e1510_config_aneg,
                .read_status = &marvell_read_status,
                .ack_interrupt = &marvell_ack_interrupt,
                .config_intr = &marvell_config_intr,
                .did_interrupt = &m88e1121_did_interrupt,
                .resume = &genphy_resume,
                .suspend = &genphy_suspend,
                .driver = { .owner = THIS_MODULE },
