* stm32: Use stm32f0_serial.c on stm32h7 chipsKevin O'Connor2022-10-313-110/+36
| | | | | | | The stm32h7 uses similar usart hardware as the stm32f0 and stm32g0 chips. Use the same code implementation for all these chips. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stm32: fix USART ORE status flag handlingAlex Voinea2022-10-313-3/+8
| | | | | | | | | | | If an USART RX overrun happened on a stm32g0/f0/h7, the ORE flag would get set by hardware. This flag would also trigger an interrupt. The problem was that this flag was never cleared on these 3 mcu families since the ORE flag clear sequence is different to all of the older chips. Since the ORE flag is not used in any meaningful way anyway, it was disabled during the init sequence. Signed-off-by: Alex Voinea <voinea.dragos.alexandru@gmail.com>

* stm32: Add Hardware PWM support for STM32G0 processors (#5714)Ben Jackson2022-09-013-4/+66
| | | | | | | | | | | Uses existing common code for STM32. Adds a table for device- specific PWM mappings. Adds support for enabling all TIM timer devices. Makes it a runtime error to enable devices the code doesn't know how to enable. I have verified performance of the fan pins (PC6, PC7, PB15) on the SKR Mini E3 V3.

* stm32: Use new CONFIG_USB to determine if USB needs to be configuredKevin O'Connor2022-08-164-10/+9
| | | | | | | | | | | | 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>

This is in preparation for adding "usb to canbus bridge mode". Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

* canbus: Use single method for reading canbus messagesKevin O'Connor2022-06-162-156/+48
| | | | | | | | | | | | Previously the code had canbus_read() which was called from task context (for admin messages), and canbus_process_data() which was called from irq context (used for data messages). Change that to a single canbus_process_data() function that is called from irq context (used for all messages). This simplifies the low-level hardware specific canbus code and should make it easier to support other hardware implementations. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
