Sorry, look like I missed to include the phy-id reported in this patch
and only included that detail in the related device tree patch [1].

This PHY seem to be different compared to the PHY used in older SoCs.

The PHY identified on addr 0x2 as 0044.1400 and in vendor kernel this
relate to the Rockchip RK630 PHY [2].

  #define RK630_PHY_ID				0x00441400

  /*
   * Fixed address:
   * Addr: 1 --- RK630@S40
   *       2 --- RV1106@T22
   */
  #define PHY_ADDR_S40				1
  #define PHY_ADDR_T22				2
