-/* AT803x supports either the XTAL input pad, an internal PLL or the
- * DSP as clock reference for the clock output pad. The XTAL reference
- * is only used for 25 MHz output, all other frequencies need the PLL.
- * The DSP as a clock reference is used in synchronous ethernet
- * applications.
- *
- * By default the PLL is only enabled if there is a link. Otherwise
- * the PHY will go into low power state and disabled the PLL. You can
- * set the PLL_ON bit (see debug register 0x1f) to keep the PLL always
- * enabled.
