shared/runtime/mpirq: Check separate hard IRQ stack correctly.
On the zephyr port, hard IRQ handlers run with a separate stack on a different thread, so each call to mp_irq_dispatch() and mp_irq_handler() has to be wrapped with adjustments to the stack-limit checker. Move these adjustments into the shared mp_irq_dispatch(), introducing MICROPY_STACK_SIZE_HARD_IRQ which a port can define to non-zero if it uses a separate stack for hard IRQ handlers. We only need wrap the hard dispatch case. This should reduce binary size on zephyr without affecting other ports. Signed-off-by: Chris Webb <chris@arachsys.com> |

zephyr/machine_timer: Support hard IRQ timer callbacks.
machine.Timer() has inconsistent behaviour between ports: some run callbacks in hard IRQ context whereas others schedule them like soft IRQs. As on the rp2 port, add support to the zephyr port for a hard= argument to explicitly choose between these, setting the default to False to match the existing behaviour. Adjust the stack-limit check to use the ISR stack while the callback is dispatched so that hard IRQ callbacks work, as with machine_pin.c and machine_i2c_target.c IRQ callbacks.

zephyr/machine_timer: Make machine.Timer id argument optional.
With a default of -1, for soft timer. This matches other ports, and the `extmod/machine_timer.c` implementation. This change allows the `tests/extmod/machine_soft_timer.py` test to pass. Signed-off-by: Damien George <damien@micropython.org> |

Simple `machine.Timer` implementation in-line with the rest of the MicroPython ports. Note: Only virtual timers are supported (not linked to any particular hardware peripheral). Tested with the nRF5340 and the nRF52840. Signed-off-by: danicampora <danicampora@gmail.com> |
