Description

.. code-block:: none

   STM32 HSI Clock node description for STM32G0 devices
   On STM32G0, HSI is a 16MHz fixed clock.

   It also produces a HSISYS secondary clk which can be used as system clock
   source. In that case, a HSI divisor (ranges from 1 to 128) can be applied:
   SYSCLK = HSI16 / HSI DIV
         enum:
         - 1 ==> HSISYS = 16MHZ
         - 2 ==> HSISYS = 8MHZ
         - 4 ==> HSISYS = 4MHZ
         - 8 ==> HSISYS = 2MHZ
         - 16 ==> HSISYS = 1MHZ
         - 32 ==> HSISYS = 0.5MHz
         - 64 ==> HSISYS = 0.25MHZ
         - 128 ==> HSISYS = 0.125MHz
