I have Variscite board available with me (var-som-mx6 board) and I am trying to develop custom driver for the ethernet (with out using any linux or u-boot). As if some one already fimiliar with the board, there are two PCBs mounted, one is Processor board and another one is base board. The Processor board bears PHY (KSZ9031) which is very similar to the phy used in sabre_lite board (KSZ9021) and also share same Ethernet controller used in Sabre_lite but the problem is that there are no schematics available for the processor board so in order to develop the driver first thing I need to figure out is the connection between the processor and the PHY but unfortunately I could not find its datasheet any where, also requested multiple times to variscite but there is no response from them. I also thought of doing PIN MUX through git but there are no specific information available. If any body could help me figure out the PIN CONNECTION or could provide me the source for linux driver for var-som-mx6 would be very highly appreciated. Thank you in advance.
