[PATCH v3 0/6] Add nRF51 DETECT signal with test

[Chris Laplante]

This patch series implements the nRF51 DETECT signal
in the GPIO peripheral. A qtest is added exercising the signal.

To implement the test, named out-GPIO IRQ interception had to be added
to the qtest framework. I also took the opportunity to improve IRQ
interception a bit by adding 'FAIL' responses when interception fails.
Otherwise, it is frustrating to troubleshoot why calls to
qtest_irq_intercept_out and friends appears to do nothing.

Testing
=======
Passes 'make check'

Changelog
=========
v2: factor out qtest_install_gpio_out_intercept before usage (Peter)
    renamed qtest_install_gpio_out_intercepts => 
qtest_install_gpio_out_intercept
    don't pass DETECT to soc level (Peter)
    change qtest to use DETECT at GPIO level (Peter)

v3: formatting fixup (Peter)
    handle multiple named out-GPIOs, not just one (Peter)

Chris Laplante (6):
  hw/gpio/nrf51: implement DETECT signal
  qtest: factor out qtest_install_gpio_out_intercept
  qtest: implement named interception of out-GPIO
  qtest: bail from irq_intercept_in if name is specified
  qtest: irq_intercept_[out/in]: return FAIL if no intercepts are
    installed
  qtest: microbit-test: add tests for nRF51 DETECT
