Well it's the board reference clock. Typically this is a crystal, but can also be an accurate, external reference or a VCTCXO so it didn't feel right to encode that into the name for the SoC DTSI. I guess it could be called board_clk if that makes things easier though. Jamie

The PC7302 board can be populated with either a PC3X2 or PC3X3 device. Add DTS files for both variants of the PC7302.
