* stm32: Use new CONFIG_USB to determine if USB needs to be configuredKevin O'Connor2022-08-161-2/+2
| | | | | | | | | | | | Introduce a CONFIG_USB build symbol that is set whenever CONFIG_USBSERIAL or CONFIG_USBCANBUS is set. Use that symbol during setup so that the USB controller is properly initialized for both usb serial and usb canbus bridge configurations. This fixes the clock configuration for usb canbus bridge mode on stm32f446. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* usb_cdc: Rename usb_request_bootloader() to bootloader_request()Kevin O'Connor2022-07-291-4/+4
| | | | | | | Rename this board API function to a more generic name. This is in preparation for calling the function from the canbus code. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* armcm_reset: Add a armcm_reset.h header file for try_request_canboot()Kevin O'Connor2022-06-041-0/+1

* stm32: Unify enable_pclock() codeKevin O'Connor2021-12-301-39/+15
| | | | | | | | | Unify the handling of the enable_pclock() and is_enabled_pclock() code across all stm32 chips. All chips will now perform a peripheral reset on enable_pclock() (this is a change for stm32f0 and stm32h7). The enable_pclock() code will now also disable irqs during the enable.

* stm32: Reorganize usb bootloader code in stm32f4.cKevin O'Connor2021-12-231-30/+63
| | | | | | Reorganize stm32f4.c into major code blocks. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stm32: Add new gpioperiph.c file for gpio_peripheral() codeKevin O'Connor2021-12-231-26/+1
| | | | | | | | The gpio_peripheral() code is the same in stm32f0.c, stm32f4.c, and stm32h7.c. Move that function to a new gpioperiph.c file to avoid code duplication. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stm32f4: reset peripherals in enable_pcclock()Eric Callahan2021-11-081-0/+7
| | | | | | | Reset peripherals to after enabling to clear stale registers set by the bootloader. Signed-off-by: Eric Callahan <arksine.code@gmail.com>

* stm32: Add an MACH_STM32F4x5 alias for F405, F407, and F429 chipsKevin O'Connor2021-10-061-4/+2
| | | | | | | | | The F405, F407, and F429 chips are in the same series and almost all code definitions should apply to all chips in that series. Implement the alias and fix defintions in adc.c and Kconfig that were only applying to a subset of that series. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
