  "message": "Rework I3C driver to runtime-bus model with register facade\n\nOne driver type now manages all four bus instances: the Instance\ntype-parameter and its per-bus impl macro are removed, and the bus is\nselected at runtime in I3cRegisters::new(bus), mirroring the SmcRegisters\nshape. All I3C MMIO unsafe (pointer derefs) is confined to the new\nregisters.rs; hardware.rs accesses the blocks through safe delegates.\n\nIRQ ownership moves to the integration layer: enable_irq/disable_irq are\ndropped from the hardware traits and the driver only exposes\ndispatch_i3c_irq plus an i3c_bus_interrupt(bus) mapping for the NVIC line\nthe kernel owns. The per-bus handler registry becomes single-shot\n(typed Busy on a second claim) and panic-free (UnsafeCell + critical\nsection, same rationale as the IBI rings, whose closure-based access is\nalso replaced by leaf push/pop helpers).\n\nThe controller is rebuilt around an ISR-shared I3cCore pinned at a\n\u0027static address, so the trampoline pointer\u0027s validity is type-guaranteed\nrather than a convention, with a light two-state lifecycle\n(Uninitialized -\u003e start() -\u003e Ready) matching the SMC precedent. Tests\nconstruct the core via cortex_m::singleton!, which also moves the large\nconfig off the 2 KiB bootstrap stack, and unmask the NVIC line\nthemselves after start().\n",
