    boards/stm32h7s8-dk: Describe the X3 HSE oscillator.
    
    HSE comes from the X3 24 MHz oscillator on PH0 (bypass mode), not from
    the ST-LINK MCO.

 /* The STM32H7S8-DK board provides the following clock sources:
  *
- *   MCO: 24 MHz from the ST-LINK is available as the HSE input
+ *   X3:  24 MHz oscillator on OSC_IN (PH0), HSE bypass mode
  *   X2:  32.768 kHz crystal for LSE
  *
- * HSI is selected by default so that the board can run when the ST-LINK is
- * not supplying its MCO clock.  CONFIG_STM32H7S8_DK_USE_HSE selects the
- * 24 MHz bypass clock instead.
+ * HSI is selected by default.  CONFIG_STM32H7S8_DK_USE_HSE selects HSE.
