Subject[net-next,v1, 0/1] Enable SERDES power up/down
Date
This patch is to enable Intel SERDES power up/down sequence. The SERDES
converts 8/10 bits data to SGMII signal.
1.Introduced 2 new BSP callbacks ->serdes_powerup() and ->serdes_powerdown().
2.The 2 new BSP callbacks is called in stmmac_dvr_probe() and
stmmac_resume() for SERDER powerup; stmmac_dvr_remove() and
stmmac_suspend() for SERDES powerdown.
3.Intel platform specific SERDES powerup and powerdown sequence functions
are added in dwmac-intel.c.
4.Since configuring the SERDES is through mdio, mdio communication is
needed to be up before powerup sequence. As for SERDES power-down
sequence, it must be configured after all dma stop and before unregister
the mdio bus.
5.New file dwmac-intel.h is created for register definition.
