In my custom board, which is based on P2040rdb, i want to change some TBI registers in linux. In order to disable TBI-phy autonegotiation. But i'm not getting how to access TBI registers. Basically serdes initialization should happen in dtsec_init_phy () before of_phy_connect () function ["drivers/net/ethernet/freescale/dpa/mac-api.c"]
I have done changes in u-boot function called: dtsec_configure_serdes () ["drivers/net/fm/eth.c"]
Can any one pls tell me any where is the equivalent function of dtsec_configure_serdes () in linux ?? or how to access TBI registers from linux.
Note: SDK: Linux-3.8.13-rt9-QorIQ-SDK-V1.4
Any help would be highly appreciated.
