Description
***********



.. code-block:: none

   Main PLL node binding for Connectivity line devices (STM32F105/STM32F107)

   Takes one of clk_hse, pll2 or clk_hsi as input clock.
   When clk_hsi is used a fixed prescaler is applied. When input clock is hse or
   pll2, configurable prescaler is used.

   Output clock frequency can be computed with the following formula:

     f(PLLCLK) = f(PLLIN) x PLLMUL         --> SYSCLK (System Clock)

     with, depending on the case:
             f(PLLIN) = f(input_clk) / 2       if input_clk = clk_hsi
             f(PLLIN) = f(input_clk) / PREDIV  if input_clk = clk_hse or pll2

   The PLL output frequency must not exceed 72 MHz.
