raiden00pl e9ac37e427 !arch/arm/src/stm32: unify the timer input clock board options ... Replace the divergent board conventions for the timer input clock frequency with a single uniform convention provided by every board: - STM32_APBx_TIMn_CLKIN and BOARD_TIMn_FREQUENCY -> STM32_TIMn_CLKIN - STM32_APBx_LPTIMn_CLKIN, BOARD_LPTIMn_FREQUENCY and STM32_LPTIMn_FREQUENCY -> STM32_LPTIMn_CLKIN - STM32_APB1_THRTIM1_CLKIN and BOARD_HRTIM1_FREQUENCY -> STM32_HRTIM1_CLKIN All STM32 consumers (tim/lptim/pwm/adc/dac/capture/sdadc/dfsdm/ pulsecount) updated to match; the timer input clock is now bus-agnostic in the drivers. Boards that carried the same timer clock in more than one convention now define STM32_TIMn_CLKIN exactly once, derived from the APB bus clock (PCLKx with the x2 doubler when the APB prescaler is greater than 1), instead of redefining it with a second, sometimes different, value. BREAKING CHANGE: The timer input-clock board macros STM32_APBx_TIMn_CLKIN, BOARD_TIMn_FREQUENCY, STM32_APBx_LPTIMn_CLKIN, BOARD_LPTIMn_FREQUENCY, STM32_LPTIMn_FREQUENCY, STM32_APB1_THRTIM1_CLKIN and BOARD_HRTIM1_FREQUENCY are removed in favor of STM32_TIMn_CLKIN, STM32_LPTIMn_CLKIN and STM32_HRTIM1_CLKIN. Out-of-tree boards must define the new macros (drop the APB bus from the name, keep the value), and out-of-tree drivers referencing the old names must be updated.
