[PATCH v4 0/3] Add device STM32L4x5 EXTI


From: Inès Varhol
Subject: [PATCH v4 0/3] Add device STM32L4x5 EXTI
Date: Thu, 28 Dec 2023 17:06:29 +0100

Changes from v3 to v4:
- add a test to check that irq trigger selection works correctly
(`test_edge_selector`) and correct `stm32l4x5_exti_set_irq` accordingly
- update the documentation file

Changes from v2 to v3:
- corrected the license to GPL

Changes from v1 to v2:
- correct the commit messages
- remove a misleading comment

Changes from v3 to v1:
- separating the patch in 3 commits
- justifying in the commit message why we implement a new model instead
of changing the existing stm32f4xx_exti
- changed irq_raise to irq_pulse in register SWIERx write
(in `stm32l4x5_exti_write`) to be consistent with the irq_pulse in
`stm32l4x5_exti_set_irq` (and also both these interrupts are
edge-triggered)
- changed the license to GPL

Changes from v2 to v3:
- adding more tests writing/reading in exti registers
- adding tests checking that interrupt work by reading NVIC registers
- correcting exti_write in SWIER (so it sets an irq only when a bit
goes from '0' to '1')
- correcting exti_set_irq (so it never writes in PR when the relevant
bit in IMR is '0')

Changes from v1 to v2:
- use arrays to deduplicate code and logic
- move internal constant `EXTI_NUM_GPIO_EVENT_IN_LINES` from the header
to the .c file
- Improve copyright headers
- replace `static const` with `#define`
- use the DEFINE_TYPES macro
- fill the `impl` and `valid` field of the exti's `MemoryRegionOps`
- fix invalid test caused by a last minute change
