## Summary This commit introduces a timer capture driver for the STM32H7 series ported from the STM32 F series. The current implementation is based on a driver originally for PWM input, and as such, it calculates duty cycle and frequency. It is also limited to a single capture channel per timer. This serves as a foundation for future development of more comprehensive input capture capabilities on STM32H7 platforms. The main changes include: - A new generic timer capture driver for STM32H7. - A lower-half driver to integrate with the NuttX capture subsystem. - Kconfig options to enable and configure capture for various timers. - Pin definitions for TIM1-4 capture inputs on the nucleo-h743zi. - An update to `cap_register_multiple` to handle multiple device registration. - An update to `stm32_bringup` to register the capture drivers. ## Impact STM32H7 users can now use the timer capture devices after enabling them in menuconfig. ## Testing Tested by polling and reading `/dev/cap0-4` with `ioctl(fds[i], CAPIOC_FREQUENCE, freq)` while sending a square wave signal to appropriate pins and checking frequency. -- This is an automated message from the Apache Git Service.
