Hi,

thanks for your support to move forward,

As per your provided input information i have made the changes as i mention below

Step:1

i have create the structure for my phy chip in alter_avalon_tse.c as show below

alt_tse_phy_profile ADIN1200 = {"AD ADIN1200", /* AnalogDevice ADIN1200 */
ADIN1200_OUI, /* OUI */
ADIN1200_MODEL, /* Vender Model Number */
ADIN1200_REV, /* Model Revision Number */
0, /* Location of Status Register */
0, /* Location of Speed Status */
0, /* Location of Duplex Status */
0,
0, /* Location of Link Status */
&ADIN1200_link_status_read /* Function pointer to configure Marvell PHY */
};
/* add supported PHY to profile */
alt_tse_phy_add_profile(&MV88E1111);
alt_tse_phy_add_profile(&MV88E1145);
alt_tse_phy_add_profile(&DP83865);
alt_tse_phy_add_profile(&DP83848C);
alt_tse_phy_add_profile(&PEF7071);
alt_tse_phy_add_profile(&ADIN1200);
step2:i have created function as per datasheet details as shown below

alt_u32 ADIN1200_link_status_read(np_tse_mac *pmac) {
alt_u32 link_status = 0;
alt_u32 reg_status = IORD(&pmac->mdio2.reg1a, 0);

/* If speed == 100 Mbps */
if(reg_status & 0x0100) {
link_status |= 0x4;
}
/* Else speed = 100 Mbps */
else {
link_status |= 0x8;
}

/* If duplex == Full */
if(reg_status & 0x0080) {
link_status |= 0x1;
}

return link_status;
}

step 3:i have add a structure for reg mapping in altera_eth_tse_regs.h as mentioned above with my phy chip

i hope i have done all modification done properly to my make my phy to work for ping application. If anything missing or anything need to correct let me known
