+ * AMI FS6377 Clock Generator configuration table
+ *
+ * the "fs6377_regs[]" table entries correspond to FS6377 registers
+ * 0 - 15 (total of 16 bytes).
+ *
+ * the data is written to the FS6377 via the i2c bus using address in
+ * "fs6377_addr" (address is 7 bits - R/W bit not included).
+ *
+ * The fs6377 has four clock outputs: A, B, C and D.
+ *
+ * Outputs C and D can each provide two different clock outputs C1/D1 or
+ * C2/D2 depending on the state of the SEL_CD input which is connected to
+ * the MPC8260 I/O port pin PA11. PA11 output (SEL_CD input) low (or 0)
+ * selects C1/D1 and PA11 output (SEL_CD input) high (or 1) selects C2/D2.
+ *
+ * PA11 defaults to output low (or 0) in the i/o port config table above.
+ *
+ * Output A provides a 100MHz for the High Speed Serial chips. Output B
+ * provides a 3.6864MHz clock for more accurate asynchronous serial bit
+ * rates. Output C is routed to the mezzanine connector but is currently
+ * unused - both C1 and C2 are set to 16MHz. Output D is used by both the
+ * alt-input and display mezzanine boards for their video chips. The
+ * alt-input board requires a clock of 24.576MHz and this is available on
+ * D1 (PA11=SEL_CD=0). The display board requires a clock of 27MHz and this
+ * is available on D2 (PA11=SEL_CD=1).
+ *
+ * So the default is a clock suitable for the alt-input board. PA11 is toggled
+ * later in misc_init_r(), if a display board is detected.
