TI asked us to replace phy_read_mmd" command with "phy_write_indirect" assuming that our kernel version 4.9 is not compatible with 812 driver.
After making the above changes the error -95 is gone but the register 0x45d reads all 0's instead of expected 0x2280 (pins LED_0 -- LED_1 -- RX_D2 have external 2.49k pull-ups to 1.8V VDDIO)
