* rp2040: Fix watchdog enableKevin O'Connor2022-11-191-0/+3
| | | | | | | | | | | | The rp2040 watchdog does not actually reset anything by default. The psm_hw->wdsel field must be programmed to actually get a reset on a watchdog failure. Program that field so the watchdog is usable. Also, disable the watchdog before attempting a reboot into the bootloader. Otherwise the machine may just reboot a second time due to a missed watchdog event in the bootloader. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

* 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: Use new CONFIG_USB to determine if USB needs to be configuredKevin O'Connor2022-08-165-12/+14
| | | | | | | | | | | | 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>

* mcu: Delay reset signaling for usb to canbus bridge nodesKevin O'Connor2022-07-291-0/+3
| | | | | | | | An mcu device acting as an "mcu bridge" should only be reset after other normal devices are reset - otherwise the bridge wont be able to pass along the reset message to the downstream mcus. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
