Type: bug
Calling `timer_init()` with unsupported frequencies on some MCUs just selects the closest possible frequency. But e.g. on SAM0, using an unsupported frequency will cause `timer_init()` to fail; which probably is the better option. However, a failing calling to `timer_init()` results in a test failure. This is now worked around by using timer_query_freq() to select a suitable timer frequency that is supported.
The GPIO IRQ tests had a side-effect that IRQs remained configured after the test case was complete. This caused stray IRQs to trigger on SAM0 MCUs and they consequently (and incorrectly) failed the test.

Contribution description
Regarding Invalid Calls to
timer_init()Calling
timer_init()with unsupported frequencies on some MCUs just selects the closest possible frequency. But e.g. on SAM0, using an unsupported frequency will causetimer_init()to fail; which probably is the better option.However, a failing calling to
timer_init()results in a test failure. This is now worked around by using timer_query_freq() to select a suitable timer frequency that is supported.Regarding GPIO IRQ Tests
The GPIO IRQ tests had a side-effect that IRQs remained configured after the test case was complete. This caused stray IRQs to trigger on SAM0 MCUs and they consequently (and incorrectly) failed the test.
Testing procedure
On e.g.
wemos-zeroorarduino-zerothe test should now run to completion and - with the exception of the ADC tests - pass.In
masterGPIO IRQ tests will fail and the test will abort after a failing call totimer_init().Issues/PRs references
