/* Clocking *************************************************************************/
/* Four clock sources are available on STM3240G-EVAL evaluation board for
* STM32F407IGH6 and RTC embedded:
*
* X1, 25 MHz crystal for ethernet PHY with socket. It can be removed when clock is
* provided by MCO pin of the MCU
* X2, 26 MHz crystal for USB OTG HS PHY
* X3, 32 kHz crystal for embedded RTC
* X4, 25 MHz crystal with socket for STM32F407IGH6 microcontroller (It can be removed
* from socket when internal RC clock is used.)
*
* This is the "standard" configuration as set up by arch/arm/src/stm32f40xx_rcc.c:
* System Clock source : PLL (HSE)
* SYSCLK(Hz) : 168000000 Determined by PLL configuration
* HCLK(Hz) : 168000000 (STM32_RCC_CFGR_HPRE)
* AHB Prescaler : 1 (STM32_RCC_CFGR_HPRE)
* APB1 Prescaler : 4 (STM32_RCC_CFGR_PPRE1)
* APB2 Prescaler : 2 (STM32_RCC_CFGR_PPRE2)
* HSE Frequency(Hz) : 25000000 (STM32_BOARD_XTAL)
* PLLM : 25 (STM32_PLLCFG_PLLM)
* PLLN : 336 (STM32_PLLCFG_PLLN)
* PLLP : 2 (STM32_PLLCFG_PLLP)
* PLLQ : 7 (STM32_PLLCFG_PPQ)
* Main regulator output voltage : Scale1 mode Needed for high speed SYSCLK
* Flash Latency(WS) : 5
* Prefetch Buffer : OFF
* Instruction cache : ON
* Data cache : ON
* Require 48MHz for USB OTG FS, : Enabled
* SDIO and RNG clock
