Extends itr_chip framework to allow interrupt controllers to register
as interrupt chip and other interrupt management methods it their
owns interrupt consumer through the interrupt_xxx() API function.
This change does not modify the existing interrupt API function that
allow a driver to get an interrupt from the CPU main interrupt controller.
A later change will remove these old API functions.
This changes adds fields in existing structures defined in interrupt.h:
- itr_handler::chip back references the interrupt controller
- itr_chip::handlers is a list head for controller registered handlers
- itr_chip::name for debug trace purpose
- itr_ops::mask and itr_ops::unmask to mask/unmask an interrupt
The new API functions exposed to interrupt consumers are:
- interrupt_add_configure_handler(), interrupt_remove_handler() and
helper functions interrupt_add_handler() and
interrupt_add_handler_with_chip();
- interrupt_alloc_add_handler() and interrupt_remove_free_handler();
- interrupt_configure(), interrupt_enable(), interrupt_disable(),
interrupt_mask() and interrupt_unmask();
Interrupt controllers shall call generic API function
interrupt_call_handlers() to have their registered consumer handlers
called upon their related interrupt occurrences.
