Add HSE,HSI,CSI,PLL as system clock options.
Also add correct configuration of the PLL.
New sysclk options:
- HSI with: CONFIG_CLOCK_STM32_SYSCLK_SRC_HSI=y
- HSE with: CONFIG_CLOCK_STM32_SYSCLK_SRC_HSE=y
- CSI with: CONFIG_CLOCK_STM32_SYSCLK_SRC_CSI=y
Existing sysclk options:
- PLL with: CONFIG_CLOCK_STM32_SYSCLK_SRC_PLL=y
PLL clock options:
- More PLL source clocks:
Existing:
1. HSE with: CONFIG_CLOCK_STM32_PLL_SRC_HSE=y
New:
2. HSI with: CONFIG_CLOCK_STM32_PLL_SRC_HSI=y
3. CSI with: CONFIG_CLOCK_STM32_PLL_SRC_CSI=y
- PLL vco input range is auto-calculated based on PLL DIVM1
-> Example for sysclock 96MHz generated with PLL from HSI
CONFIG_CLOCK_STM32_PLL_SRC_HSI=y
CONFIG_SYS_CLOCK_HW_CYCLES_PER_SEC=96000000
CONFIG_CLOCK_STM32_SYSCLK_SRC_PLL=y
CONFIG_CLOCK_STM32_PLL_M_DIVISOR=4
CONFIG_CLOCK_STM32_PLL_N_MULTIPLIER=12
CONFIG_CLOCK_STM32_PLL_P_DIVISOR=2
CONFIG_CLOCK_STM32_PLL_Q_DIVISOR=4
CONFIG_CLOCK_STM32_PLL_R_DIVISOR=2
Use LL_SetFlashLatency function from stm32h7xx_ll_utils.h
instead to setup the correct latency.
