[PATCH v2] davinci: RMII support for DA850/OMAP-L138 EVM

2009-09-22 Thread Chaithrika U S
DA850/OMAP-L138 EVM has a RMII Ethernet PHY on the UI daughter card. The PHY is enabled by proper programming of the IO Expander (TCA6416) ports. Also for RMII PHY to work, the MDIO clock of MII PHY has to be disabled since both the PHYs have the same address. This is done via the GPIO2[6] pin. Thi
