* stm32g4: implement build,usb,can,i2c,spi,serial,adc.Matt Baker2022-12-021-4/+17

* stm32: Use stm32f0_serial.c on stm32h7 chipsKevin O'Connor2022-10-311-3/+35
| | | | | | | 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 Voinea2022-10-311-1/+2
| | | | | | | | | | | 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: Support PB7/PB6 for USART1 on stm32f0Kevin O'Connor2021-08-011-6/+16
| | | | | | | | | | | Add support for USART1 on PB7/PB6. Remove STM32_SERIAL_USART1_ALT_PA15_PA14 option and allow all serial mappings to be used on stm32f031. Reported by @Desuuuu. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
