[PATCH v3 0/3] Connect STM32L4x5 USART devices to the EXTI

Posted by Inès Varhol 4 months, 2 weeks ago

STM32L4x5 EXTI was handling only configurable interrupts
(such as those coming from STM32L4x5 SYSCFG which was the
only device connected to the EXTI).
This patch adds support for direct line interrupts and
connects the existing STM32L4x5 USART devices to the EXTI.
The patch also corrects the handling of configurable line
interrupts in the EXTI.

Changes from v2 (2nd commit):
- The 2nd commit was split, part of the changes went in
another patch correcting EXTI configurable interrupts.
Stayed in the commit only changes relevant to direct interrupts.

Changes from v1 (2nd commit):
- add STM32L4x5 EXTI status fields `irq_levels` to track
configurable irq levels and do edge detection
- use `qemu_set_irq` instead of qemu_irq_raise/lower

Applied to target-arm.next, thanks.
